Hm, okay then. But anyway, RIP inventory and everything else.
Well, why i am still not banned then? I guess you can't play at any VAC-secured games anymore, not only Rust.
Seems your friend has installed cheats and got banned. Even though you didn't used cheats, your account will be banned forever, and you can't remove this ban. Do not give any accounts to your friends if you don't trust them or they want to install some "mods" like these. btw...
