Have you ever been in a LFG where the group is "against" you for whatever reason, and you know it's only a matter of time before they vote kick you? Well, to prevent this/get revenge on them, vote kick one of them and in the vote kick description box write "Vote kick (your name)" (for example, if your character name is Bob you would write "Vote kick Bob"). They will think they are vote kicking you, but will actually be vote kicking themselves lol. Plus there is a limit of 1 vote kick per dungeon, so they can't vote kick you afterwards. This has a 100% success rate for me, I did it earlier today in a group with a dickwad tank and his friends, they were pretty upset after realizing they had kicked the wrong person LOL.
