last week 60 of 300 accounts got a complete follow and like and comment block.
I changed proxy, removed link etc. but cant solve the problem until now.
I just delete the bio description and write the same again and all my blocks are gone.
Maybe this can help you.
since today i cant verificate my accounts, i type in the number from smspva, after i accept instagram show me "please choose another number" – if i repeat that i got an instant bann on this account – got the same problem with 4 accounts so far .
This method has worked very well for over a year for me, someone got the same problem?
