SethHack and server ownership questions!

Hello, I have a quick question. I’m a server owner and I want to start developing and testing a SethHack anti-cheat which will require me having to BUY and USE SethHack. If I do this will I be at risk of being banned for Garry’s Mod? If so, are there any functional and free anti-cheats out there?

Disable VAC on your server.
Disable server purity (I think that’s what garry called it)

Or you could get the LUA version.

Get the Lua version, and load it before your anti-cheat.

I hope you know that you’re posting your Steam Profile on a public forum, of which the owner of SethHack frequents. You’ll probably be unable to buy SethHack at this point, unless you use a different Steam account.
