There is this player, who is 13 years old keeps causing arguments, with players and me myself. I've decided that it can't go on so I've banned him. After banning, he tried using VPNs, using multiple alts accounts (even tho its Online-mode), using hack clients, world downloader to download my spawn and threatening to upload it, he also used some form of hacked client, that I'm not so aware of to get my plugin list, leaking it to everyone. I'd be very grateful if someone could help me deal with this situation. It's been 3 constant days and he won't stop.
