Hey people! You all asking about who makes the checks, or limiting the feature. But I had a great idea!!!!1!

Why instead, when that happens, all innocent players will file a player harassment petition?
This will have all good consequencies! First, if petition is handled, the smart player having fun with check, will have fun with his/her account sanctioned then, for the greater good! Second, if petitions sent to SE will reach a good amount of, I'm sure that this will become a priority in the development team, just to lessen the pressure on support team.

Yes, I am evil!
