Until you actually implement in-game report features, (which should have been already programmed in before launch), I would suggest you;
Add ping limiters to servers, i.e 0-90 which would disallow most of the cheat users (we won't name locations) from even accessing the servers. It's quite obvious the amount of hack using players are over taking the server to the point of where you lose players everyday, and frustrate even more on a regular basis. And no, for all the players who say "these are just good players better than you". No, pro players don't move like bots. Any experienced FPS/BR player can tell the difference between a pro players movements and an aimbot user.
Fix your game before you ruin your reputation.
