I purchased accounts from the seller i usually purchase ( they were good before )
only thing i did on them is
1. changed password.
2. changed cover and image
3. updated channel description( no hack words and things )
4. uploaded my own gameplay with royalty free music.

tomorrow when i wanted to login i got that message on login.
However Channel is still alive and i can watch the videos on it etc...
but its impossible to login as i get that message

Anyone know what could this be ? bad accounts or what
( also for those who say its ip ( i had multiple accounts done from multiple clean ip and they all got same )

usually there is 3 strikes if they do not like what you upload etc..

I never encountered something like this on "clean" account

Maybe the proxy issue I guess.

Maybe the proxy issue I guess.

hardly as accounts from other seller are still alive and standing
