Im running pages in different niches (completely normal and white themed), following meta guidelines, i was switching between them in a same accounts center and then i unfollowed around 25 people using one of the pages and it got suspended and caused a chain suspension in other pages too. After that some got disabled due to integrity, some got recovered, and i also used same emails and numbers for a couple pages. I already understand i made every mistake possible to trigger AI, and lose accounts one by one. Now i want to make a max reliable setup, separate mobile numbers for each page, separate email, no linking in accounts center, only thing that seems useful and is expensive is proxy, i'd prefer making a setup avoiding it somehow. Is it possible?
What you've mentioned here in this comment, shows no sign for which meta might be banning your accounts. I personally also keep over a half a dozen accounts on my personal phone at once, and even follow/unfollow over a 300 accounts in 1 go when needed. With 0 repurcussions from the meta side. 25 accounts unfollow action is nothing. You're missing something. Maybe some of your account got hacked and was used for spamming somewhere behind the scenes without your knowledge? Or maybe you logged in those accounts in some spammy software or something?
Because meta themselves officially allow 10 accounts in their official app. And I personally have dozens of accounts that I know are linked, in 1 way or the other (I've managed them from my personal phone/IG app.) Only thing being, I was not doing/don't do anything spammy. And my accounts stay just fine.
From my experience, the reason for your bans is something entirely different, which you've missed. Try to look at what else might have happened/that you might have done with these accounts? (Maybe had some fight with someone, and they might have mass reported your accounts, just out of anger or venting or something like that?)
