I never said it was allowed, I said you can't ban for that. At least, that's what I've heard. Anyways, adding on to the report, I believe he ddos. I'll put pics once I upload them.
Remade report format, just in case:
1. Player's SteamID
(Same as RDMer)
2. Player's nickname
(Same as RDMer)
3. Your in-game name
blah2357
4. Server Name
TTT
5. Description of events
He said that after he died, he would ddos the server. Then the server started lagging as show in the pictures.
6. Reason for ban
Possible DDOS
7. Screenshots or demo(s) l Optional console log(s)
Oh yeah, he kept showing this link in game to everyone:
