Do I need to use a new device or is anti-detect browser with static residential proxy enough?

Buying accounts and trying to mask identity is against Facebook policy, and no setup reliably prevents linking or bans
 
That would usually be enough, but it still doesn't guarantee anything in the long run; it's like playing Russian roulette.
 
You only need to use anti-detect browser (Adspower, Dolphin,...) and use clean Proxy, it is not necessary to change to another device. The important thing is to only log in through 1 address so that Facebook does not flag unusual activity and lock the account.
 
Everyone specualting here and the OP did not bother to specify.

APP or web? Going from phone or desktop?

Very important before you can give any guidance, since the OP and everyone else was too lazy to even bother thinking this far, I will not bother to explain how which option select makes a difference.
 
Antidetect and a different IP than the one you have previously being banned will do the trick
 
Bought Facebook accounts are inherently risky. Meta uses many signals beyond device or IP, so anti-detect browsers or proxies don’t make them safe. New profiles, BMs, and ads are heavily reviewed and often banned. There’s no setup that fully minimizes risk,account trust matters most.
 
If your old account was banned due to a violation, you need a blank browser that is recognized with a proxy; switching to a new device is not necessary.
 
Yes, new accounts must be segregated. First, you need to use a completely new account environment with a clean and stable residential IP address. This is to avoid the system detecting that the account is linked to an old account and restricting it again.
 
You don't need to switch to a new device. The anti-detection browser has already changed your IP address.
 
In my experience, when I launched my ebook, I tried promoting it on various platforms and realized that if I always used the same configuration, the accounts would quickly disappear. What gave me the best results was combining an anti-detect tool with a residential proxy; in my case, I tried Bright Data. This made it look more natural without having to invest in another device. It's not foolproof, but it allowed me to keep the accounts active longer. Have you tested whether changing your device really makes that much of a difference?
 
Anti-detect browser with a static residential proxy is low risk.
 
Purchased accounts are inherently high risk. Anti-detect browsers or proxies do not guarantee safety. Best practice is self-created accounts, identity, appeals, and policy-compliant ad operations.
 
If you want to stay safe, use one clean account per platform, post original/owned content with consent, and follow each site’s verification and policy rules.
 
Buying accounts and using tools to mask identity violates Meta policies and always carries a high risk of bans, regardless of device or browser setup. The safest option is to recover your original account or create and use a legitimate account that fully complies with Facebook’s rules.
 
use antidetect browser and proxy residental or mobile
 
You can use Adspower, it's very safe and easy to use. You can use it with your old device without having to switch to a new one.
 
Actually, with such a small number of accounts, you don't need to worry too much.
 
If your old account is restricted, it's best to re-appeal or create a new, legitimate account. Facebook tracks many signals including device, IP, behavior, and payment, so simply changing your browser proxy doesn't guarantee long-term security.
