Too many cheater in WL (PC), just do something

I played 15 wl matches today, or at least I wish I could say so, I have encountered 8 people who have done the no-loss glitch and 3 people who have reset my player stats, I was forced to get 12 wins by playing 23 games out of the 15 required. Obviously their nickname was either invisible characters or randomly spammed letters, and the in-game reporting system sucks as *.
