I had some accounts got banned with the ID verification instantly after adding them to MP, If you Just spam your contents through facebook with Fresh accounts then just be sure you will get flagged sooner or later .
If you want to keep accounts for longer :
- Try maintaining a good activity - and avoid joining or posting in groups in the 1st days of using accounts, you can join 1 or 2 groups in 2 or 3 days . And use MP module to like,comment on other posts automatically to keep accounts active, don't forget to use that feature to disable the module during night .
- For automation, use always PVA accounts with Dedicated proxies . Shared proxies are the suicide squad in FB.
- When you start joining and Posting in group , do it in minimal rates , start by 2-3 groups per day for each account , and increase the amount until your accounts got Post limiting, here you know the perfect rate .
Now; after you make sure your accounts are in a good stand in Activity, it comes the second part , your content : posts . If your content get a High amounts of reports from users Or admins, Or just that a lot of admins didn't approve your post, You'll start getting warning points from facebook & if that continue , your accounts could get banned . Otherwise, if you got a good amount of likes,reactions,comments in your posts, facebook can't just ban you Even if you post the same content on multiple groups . Be creative with your leads-in & angles . that's the why to do it .
With some account I use to post manually to about 30 groups in the same hour , the same link the same content & the account don't get banned . And when I tried to post with MP, the worst thing I Got was a An Antivirus checkup, But I got my account restored after that without doing anything, just checked the accounts & found that one come back to work . (it's a NON-PVA btw)
It's hard to determine exactly how facebook algorithm work, Sometimes your account may get banned without reason & other times you do spam the shit out of facebook but nothing happens , but as long as your account look like a Normal person & do what that normal person does, and you don't spam other users with something they heat to see, you'll stay fine, Facebook cares a lot about their UX that's why they ban accts in 1st .
