Ummm, I'd recommend going and buying an account with csgo on it, you can find fresh accounts for like 5 dollars. Every server that isn't VAC secured, I've seen cheaters on. Even the ones that SAY that is isn't a hacker server. But if you really want to risk it, go in your server browser set the search to "Not Secure" servers and hit refresh, look for the ones that say "non-hvh" or something like that.
