I only say this to who really really care about rating and have patience. So some jerks gonna do some tricks (I don't wanna mention about this, u know what I mean :) )to make ur screen lag-out (freeze). Don't refresh / close / switch the browser. Wait about 3 mins (may be longer than 5 mins), ur computer is going to "calm down" and the "Victory" screen gonna pop up. It works for me all the time, but idk it works for u guys or not :)
And yes I really care about my rating above 2k because I know I gonna lose over 22 rating for losing some jerks about 1k7 or below using these tricks
