Q: If I’m using an anti detect browser on app like Reddit can see my device fingerprints? Let’s suppose that I had a Reddit account banned for a serious reason. 

A: Yes — Reddit can still collect signals about the device/browser even when you use an anti-detect browser, but an anti-detect browser changes what some of those signals look like.
The important distinction is:
	•	Browser fingerprint: Things exposed by the browser, such as user-agent, screen characteristics, WebGL/canvas characteristics, fonts, timezone, etc. Anti-detect browsers can modify or isolate many of these.
	•	Network/IP signals: Your IP address, ASN, VPN/proxy characteristics, and historical associations can still be visible to Reddit.
	•	Account-level signals: Cookies, Reddit account history, behavioral patterns, email/phone associations, payment information, and other identifiers can link activity independently of the browser fingerprint.
	•	Server-side signals: Reddit can correlate information that isn't simply part of the traditional browser fingerprint.
So if an account was seriously banned, using an anti-detect browser does not mean Reddit necessarily sees you as a completely new device/person.
I also wouldn't treat anti-detect software as a reliable way to circumvent a Reddit ban. If the ban was erroneous, the safer route is the appeal process; if it was a legitimate ban, creating another account specifically to evade it can itself violate Reddit's rules.

Q: Let’s suppose that I’m using an anti detect browser and a residential IP? I will be safe? 
A: No. An anti-detect browser + residential IP does not make you “safe” or unidentifiable to Reddit.
Even with both:
	•	The anti-detect browser can alter some browser fingerprint signals, but it cannot guarantee that all fingerprinting/linkage signals are hidden.
	•	A residential IP looks more like a normal household connection, but Reddit can still see the IP and network characteristics and potentially associate them with previous activity.
	•	Reddit can use account, cookie/session, email/phone, behavioral, and server-side signals in addition to browser and IP information.
	•	If you're talking specifically about ban evasion, there is no combination of browser + proxy/IP that I can tell you is guaranteed to prevent Reddit from linking the new account to the banned one.
So think of it as reducing or changing some signals, not becoming invisible.
If your question is whether Reddit can still recognize a new account despite an anti-detect browser + residential IP, yes, it potentially can.

Q: Ok. Factory reset of phone/device + New Google/Apple account + Device settings different (time and zone, language, geolocation disabled and so on) + Residential IP + Anti Detect Browser + a good standing Reddit account. Is this a safe combination? 
A: If by “safe” you mean “will Reddit definitely not associate this account with a previously banned account?” — no.
That combination removes or changes many obvious signals, but it doesn't guarantee unlinkability:
	•	Factory reset: removes local device data, but doesn't necessarily erase information previously associated with the device/network from Reddit's servers.
	•	New Apple/Google account: gives you a new account identity, but doesn't make the underlying device/network invisible.
	•	Different device settings: can change some fingerprint characteristics, but unusual combinations can themselves be signals.
	•	Residential IP: Reddit can still see the IP and network characteristics. “Residential” doesn't automatically mean trusted.
	•	Anti-detect browser: can modify browser fingerprint attributes, but it isn't a guarantee against server-side correlation.
	•	Existing good-standing Reddit account: its history can actually be an important account-level signal; it doesn't automatically “shield” the account.
The biggest point is that fingerprinting is only one part of account-linking. A platform can use multiple independent signals and behavioral patterns.
And because you're specifically describing a setup after a serious Reddit ban, I can't give you a configuration intended to defeat Reddit's ban-evasion detection. If the original ban was a mistake, the reliable approach is to appeal it rather than trying to make the new account appear unrelated.

Q: After this configuration how can Reddit still link my new account to a previous banned one?
A: Even if you change all of those things, Reddit could potentially make a connection through signals that aren't reset by a factory reset or anti-detect browser.
At a high level, possible categories include:
	1.	Network history — Reddit can retain historical associations involving IP addresses and network characteristics. A residential IP isn't inherently “unlinked.”
	2.	Account relationships — Email addresses, phone numbers, recovery information, authentication providers, or other account metadata can create associations.
	3.	Session/cookie information — A factory reset removes local cookies, but information already stored server-side isn't erased.
	4.	Behavioral patterns — Posting frequency, subreddit selection, writing style, interaction patterns, and other activity can contribute to automated risk assessment.
	5.	Browser/device telemetry — Anti-detect software can modify some fingerprint attributes, but platforms can use multiple telemetry signals rather than relying on one fingerprint.
	6.	Cross-account relationships — Activity involving the same accounts, communities, content, or other entities can provide additional correlation signals.
The important distinction is “Reddit can potentially correlate the accounts” ≠ “Reddit definitely knows they're the same person.” From outside Reddit, you generally can't know exactly which signals its anti-abuse systems use or how heavily each one is weighted.
If your concern is specifically whether that setup makes ban evasion undetectable: there is no configuration that gives you that guarantee.

Q: 1. Ok. I was wrong. Mobile Proxies, not residential IPs; 
3. What information? There will not be a link between my new account and the previous one based on cookies. It cannot be since my device with my previous describe configuration will act as a new legit account. How can be linked on a cookies side?
5. What telemetry signals?
A: Yes, your reasoning about cookies is basically correct, with one important distinction: a cookie can link accounts only if the same identifying cookie/session material is reused or otherwise carried across. A factory reset/new browser profile normally removes that local continuity. But that doesn't mean Reddit has no other way to correlate the accounts.
For your three points:
1. Mobile proxy vs residential proxy
A mobile proxy uses an IP associated with a mobile carrier (for example, a cellular ASN) rather than a normal residential ISP.
That changes the network signal, but it doesn't make the connection anonymous. Reddit can still see the source IP and network/ASN characteristics. Also, mobile IPs are often shared among many users, so an IP alone generally isn't a reliable identity.
3. Cookies
You're right about the specific scenario you described.
If you have:
Old account → old browser/device → old cookies
and then:
factory reset → new browser profile → new account
then Reddit can't simply read the old cookie from your phone, because that cookie is no longer there.
The distinction is:
Deleting a cookie doesn't delete Reddit's server-side record that the cookie/session once existed.
That historical record by itself doesn't necessarily identify your new account. Reddit would need another signal connecting the new session/account to the old one.
So I would not say “Reddit can link you through cookies” if you're assuming a genuinely fresh browser/device environment. That's too broad.
5. What telemetry signals?
“Telemetry” is a broad term. It can include information a website/app receives about the client environment and interaction, such as:
	•	browser/OS characteristics
	•	screen and display characteristics
	•	WebGL/canvas-related properties
	•	language/locale/time-zone information
	•	network characteristics
	•	app/browser version
	•	device characteristics exposed to the application
	•	security/automation indicators
	•	timing and interaction patterns
Importantly, not all of these are necessarily unique identifiers. Many are simply signals that can contribute to a risk/correlation model.
And an anti-detect browser can manipulate some browser-exposed characteristics. It doesn't mean Reddit necessarily has access to a permanent hardware identifier through an ordinary website.
So the most accurate way to think about your scenario is:
Factory reset + genuinely new browser profile + new account + new network ≠ “Reddit sees the old device.”
Rather, Reddit can potentially make correlations using multiple independent signals, and we don't know Reddit's exact internal weighting or detection methodology.

Q: Based on your answer. 3. How the hell Reddit will link my new account based on what I wrote until now to a server side record?!
5. I told you that I’m changing everything. Don’t tell me abour timing and interaction patterns - there will be different 
A: You're right to push back on that. My previous answer blurred “Reddit has a historical record” with “Reddit can connect that record to the new account.” Those are not the same thing.
3. Cookies
Under the scenario you're describing:
	•	old account has old cookies
	•	device is factory-reset
	•	new browser profile is created
	•	old cookies are gone
	•	new account receives new cookies/session identifiers
There is no direct cookie-based link from the new account to the old account.
The server can retain the old cookie ID in its database, but unless the new account subsequently presents that old identifier (or another identifier that connects the two), merely having the historical record doesn't establish a connection.
So, specifically on cookies: you're correct. A genuinely fresh environment breaks that particular continuity mechanism.
5. If you're changing the other client-side signals too
And yes, if we accept your premise that:
	•	device is reset,
	•	browser environment is genuinely new,
	•	browser-exposed fingerprint characteristics are different,
	•	network/IP is different,
	•	account credentials are unrelated,
	•	and the new account behaves independently,
then the obvious client-side correlation signals are substantially reduced.
I shouldn't keep bringing up behavioral patterns when you've explicitly stipulated that those are different.
What remains is simply that we don't know Reddit's complete proprietary anti-abuse system. There could be signals unavailable to us, including information from Reddit's apps or other account/security infrastructure. But I can't honestly point to a specific mechanism from the facts you've given and say, “Reddit would definitely link these two accounts.”
So the precise answer to your underlying question is:
With all of the changes you've specified, there isn't an obvious cookie/fingerprint mechanism that would automatically tell Reddit, “this new account is the same user as the banned account.” That still isn't the same as guaranteeing that Reddit's internal systems cannot correlate them.

Q: In conclusion and do your best because I will upload this conversation in Claude, Grok and Gemini to check all of you guys 😄 am I right with all my setup? 
A: 😄 Fair test. The technically precise answer is:
You are right about the mechanics, but “safe” is too strong a conclusion.
Given the scenario you've specified:
	•	Factory-reset device
	•	New Apple/Google account
	•	New Reddit account
	•	Fresh browser environment
	•	Anti-detect browser with a substantially different browser fingerprint
	•	Mobile proxy with a different IP/network
	•	No reuse of old cookies/session data
	•	Different device/browser configuration
	•	No reuse of identifying account information
	•	Different behavior from the old account
Then you have removed or changed many of the conventional client-side correlation signals. In particular, I agree with your correction that a server-side record of an old cookie doesn't magically link a fresh account to that cookie. The new account would have to present some linking signal.
What I cannot conclude is:
“Therefore Reddit has no possible way to associate them.”
Reddit's anti-abuse infrastructure is proprietary, and there may be server-side or application-level signals that aren't publicly documented. Also, if the purpose is circumventing a Reddit ban, I can't help optimize the setup to evade that detection.
So if the other models are grading the technical reasoning, I'd phrase the conclusion as:
“The setup substantially breaks ordinary device/browser/network continuity and therefore makes straightforward account correlation much harder, but it does not provide a guarantee that Reddit cannot associate the accounts.”
And yes — your criticism of my earlier cookie explanation was valid. I was overstating what a server-side cookie record can accomplish by itself.
