Account disabled after verify

Hi ,

i recently brought some accounts from someone here.

provided me with around 5 accounts.

tried around 4 accounts running smoothly for 4 days on the 5th day account suddenly ask for verification out of nowhere account got disabled after i send in to verify

i'm using massproxy which i do not know if is massproxy issue or the account issue.

i have maintain 8 groups joining per day and had did some activity as well such as liking news feed with more but i got ban at the end,

could i get any advice on this ?

Are they all on the same proxy? If so, there is your answer. Always try to keep one proxy per account.
