Can I get banned from CSS?

Sorry for my bad English.

I have heard that if you cheat at counter-strike that you then gebt banned. Do you also banned if you cheat in your own server? Therefore if make a server with create server?

Nope, but if you make your own server, you can basically just use the console to activate the hacks.

You can get banned from VAC if your using the real version they will ban your CD-key
