Detected?

So i found this hack in a website: *censord*
*delete space*
and it says its an addon, so my question is is it an undetecteble addon or just another detected hack?

I can't test this, but I'm thinking that they don't want offsite links to files here.

Urr, I don't know about that, but it "might" be if you don't have a working bypass.

VAC cannot detect LUAs from gmod,as they allowed it,even a LUA aimbot
