Why are my account is permanently restricted?

i didnt use VPN and Double account but my account got permanently restricted. after i click resend activation link my account is back to normal but they didnt give me a new password…

That is because your IP got flagged (blacklisted) as suspicious/spam. Which ironically enough is caused by the websites you receive as tasks to visit.
Check your IP score. If it is a “high risk”, stop working on this website.
