This is an exploit that's starting to become more popular. Here is an SM extension that should block
/log & kick any player that attempts to crash the server this way.
Code:
[CMDFIX] GoD-Tony (ID: STEAM_1:1:123456 | IP: 192.168.168.1:27005) was kicked for sending a corrupt user cmd.
Edit: I've removed the binary attachment as it causes crashes and I don't have time to work on it.
Edit 2: Newest version can be found at
