The server me and my friends use got hacked somehow???

So i opened a server for me and my buddies, and this guy named Bodyash joins. We don't think too much of it because it could be a buddy on an alt (you never know).

Next thing we know, he starts stealing all sorts of stuff (we're cheaters so /commands are turned on for ops, this is important for later)

I tp him to a little bedrock prison i made while tunneling out a pool, and the next thing i know he gets OP and IP bans me from the server.

Not going to show my banned IP for obvious reasons.

Is there any help i could request? I made this account just to report this and I'm kind of in a pickle with my friends.

Yeah.

wait is that the reason

oh boy.

Noted

is there any plugin you recommend using?

that's a bit of a bummer considering we're using uhh, tlauncher to do this entire thing.

Anyways, thanks for the help
