Server crashing because of someone.

I was told by my staff a little while ago that my server was crashing every so often. I go on to check it out. It was fine until this guy was autoslain, then it crashes several times. I check the logs to find this.

I have no idea what it means other than I know he is the cause of the crash.
I banned 2 of his ID’s, is there a way I can ban his IP at all?

Banning his IP isn’t going to get you very far, most people don’t have static IP’s. In addition it’s not very hard to simply change your IP. SteamIDs on the other hand are impossible to change and will remain the same regardless of ehat computer you log into.

If you are absolutely set on baning his IP you can find a banIP command for ulx here:

I ended up finding banned_ip.cfg and added him there.

SteamID normally works, but either he has 5+ accounts, as that is how many I banned before I just shut it down for the might, or he somehow changed his ID. My bet is on 6 accounts with Steam Family Share to be honest.

Also do you happen to know what the error message was and/or how it was created? My friend seems to think its a crappily coded ULX module or add-on.
