The best way is to use an Anti Detect Browser (such as AdsPower, Multilogin, Incognition..).
If the client is setting up Full Setup solution themselves (which is very difficult), the Setup must not be connected to anything that was previously associated with the blocked account (BMs, Datasets, IPs, Credit Cards etc etc).
What we are recommending is to have in 1 Setup (1 Ad acc/1 webpage):
- 3 personal accounts (bought with cookies history + possibility to make ID verification for review/ban situation)
- static residential proxies (same country as was used on the personal accounts before)
- 1 Aged/verified BM
Use every Personal account differently:
1. The media buyer (you will run the ads by that)
2. The Main admin (you will create here page, pixel etc) - you will not use this for managing ads, so 0% chance to be banned and 0% chance to lost pixel, page etc (you just sharing access to this to other accounts), so totally safe
3. The Backup admin (you are not using this, only once the "Media buyer" is restricted and while you are waiting for ID verification or manual review, you can continue with managing your Ads on this account during this time.
A lot of people just buy 1 personal account, one proxy and think they've won. But the first time they have a problem they lose all their data, pixel, FB page and start all over again.
But if you have strong Setup like we have, you will never lose anything again and with the combination with Agency Ad Acc you can stale up to thousands per day.
