Any proof?
1: Server crashing
About a week ago, he was telling me how he can crash servers with events. I dismissed that as bullstuff, but he continued to try and do it anyways. Nothing happened, but after that it was pretty obvious he had malicious intent on the server and should not be taken seriously.
2: Spammy builds

If they were 1x2 bricks i would be fine with it but this is just a little ridiculous.
3: Loading macros
A while after the "server crashing" incident, he started to load a bunch of pointless img2brick macros. None of them had anything to do with the server, so we deleted them and told him to stop. He persisted so we banned him every time he did.
Koopa, if you want to have fun, find another server, because all you do here is make everyone else's time worse.
