Fraudulent players can trick summoners into dodging games.

A new glitch was discovered in the client that players can use into tricking players to dodge games whether it be ranked or not. Upon entering champion select a summoner claims that you can put all your mastery points anywhere by clicking edit masteries then pressing space bar 3 times. This causes the masteries overlay to glitch and stay onscreen covering your champion pool. You cannot select champions while this is covering your screen and when it comes around to your turn in champion select you are forced to dodge and lose lp. People do fall for this by the way...

I used a custom game to demonstrate but this trick can be used to fool players into dodging in a ranked queue.
