faceit

Yo so I played some faceit match and people were saying someone turned of their ac, I mean can you play on faceit without the ac client enabled? If you can how can I disabled the ac and still play on faceit?

You need a very high trust factor on FaceIT (& or Steam/CS:GO sided - they probably can get these pieces of information)
Since players like NadeKing (who not cheat) had to turn it on after a match where he got reported a lot.

The key to reach this trust is to play consistently not cheating. Also, play good. If you are too bad you will get reported for griefing.
Make people giving you a thumbs up at the end of the match.

This is not a 100% way to be able to play without AC. I used my common sense. None except FaceIT knows how their Systems for this kind of stuff work.
