Keeping accounts from getting linked to each other

Running a fair number of accounts across a few platforms and my biggest worry isn't any single one getting flagged, it's them all getting tied together and going down at once.

Right now I do a separate proxy per account and separate browser profiles, but I keep reading that's not enough anymore and that they link you on payment, cookies, timing, even how you type.
Trying to figure out where the real linkage risk is vs where I'm just wasting effort.

All of these are signals, and eventually, theyll probably all be locked, at a low level of locking, but one which requires a facial KYC check, or just "a selfie" or even a CF check. across many accounts, this is a killer with almost no effort to actual genuine accounts. The providers understand this well, and will probably enact this at the very near future.

separate proxies and profiles only cover part of it… shared payments, recovery info, devices and repeated behaviour can still link accounts, so for legit work official business/team access is safer than trying to hide the connection

The reality is that without human interaction, almost all of then will eventually go down, because they were linked together, or because ai identified then as proxy accounts. It's odd that we have ai nowadays to help automate everything, and we have ai on the other side understanding patterns of ai to ban accounts. The best you could do is warm up the account, do whatever you need or want to do, and know that they will eventually go down. The good and old churn and burn (of other circles lol)

you really need to make sure there are no links via payment
machine use , and where you made them .

The real linkage risks are shared payment methods, reused recovery emails/phones, and identical behavioral patterns (like running bots on the exact same schedule). Typing biometrics and ultra-niche tracking exist, but platforms rarely enforce them unless you're doing high-level fraud.

Separate proxies and browser profiles are still 80% of the defense. To cover the rest: isolate your payment cards (use virtual VCCs per account), randomize your automation timing, and never cross-link recovery details.
