The Rust subforum rules sticky posted:
~WHAT TO DO ABOUT CHEATERS~
For random discussion and bitching about hacks, glitches, exploits, chat spam, and the people that use them, go here: http://facepunch.com/showthread.php?t=1279498
For detailing exactly how exploits and glitches are done, or exactly how people are doing stuff using hacks, go here: http://facepunch.com/forums/419
Don't use the exploit forum unless you can really offer up something helpful towards patching that stuff. If you're not sure someone is hacking or don't have anything more to say then "THEY HACKED", use the hackers discussion thread. VAC DOESN'T RUN ON REQUESTS AND IT WILL BAN THEM EVENTUALLY, SO PLEASE DO NOT WASTE OUR TIME.
It's right here.
