Why are people who are banned allowed to come back?

[MasterP]

So a few people have been banned recently. Yet they come back using an alternate account, doing the same cheating stuff they did before. How can we combat this @ sts? Shouldnt Ips be banned? so the person cannot connect to the game in any capacity? Or if we see a banned person back in the game, how can we report this? Obviously they were banned for a reason and should not be allowed back. This is a very serious issue, the buying and selling of Gold/Accounts/Igns is rife within this game and on platforms such as Line App. How can we as a community help defend against this

And Another thing how can we report people who has bought an account? Sending proof to sts support seems to be not much help. Chad sends his automated response and you do not hear about it again.

Thank You
