Not saying this game is full of cheaters, but they are a thing.
As with any free to play game, if action is taken they just make a new account, and with the current reporting system, it takes longer to report someone, than for an actual cheater to make a new email, new account, and get back into the game. Seriously, go over to the support page and see how long it takes you to find the actual ticket system.
With Steam launch on the distant horizon, the number of actual cheaters will go up exponentially, and most people arent going to go through the headache that is the Glyph ticket system. Sure it cuts out a huge number of would-be reports from someone who things playing well means cheating by having a puzzle to solve to submit a ticket, but it'd also allow so many more people to report those few actual cheaters.
