There are still so many cheaters in this game and they are not even being subtle with their cheats either.
Just hire some people with some knowledge of this game to sit down and watch Trials matches.
We should start to see a noticeable difference after awhile.
Alternativily have something like Overwatch that Cs:go has. When a player is being reported for cheating, that match in which they got reported in, gets recorded and can be reviewed by some players. You could make it better by having some of your staff members watch that match and ban that player if they did infact cheat.

So some people have been told this even for Activision side they do record every match in a game including the game the Player has been reported in. They do look over it for a while see if its true or not with their own eyes, and at times they just can't be bothered due to "Limitations" by that they mean "Even if we did report them what is gonna stop them from making another account, using money to get everything back, and continue to hack again?" In short the staff are lazy because they get Money from the hackers too either way.
