To clarify a bit of confusion, account pay history (VIP/KP spent) is not a factor when it comes to account suspension/block.
If the account is found to be associated with illegal activity it will be restricted appropriately to the kind of offence committed.
Moreover, an account restriction may happen for security concerns such as to block unauthorized access or restrain illegal item circulation. More about account suspension is found in this support article.
The staff will never suspend legit accounts, it may happen however in cases where IP is shared among users conducting illegal activity. Usually the accounts are cleared in a timely manner.
This is frustrating without doubt however I am politely asking each of you with the pending tickets to be patient with the GM team.
