Using a chat glitch to cover up or ruin other peoples posts it's strictly something people shouldn't do, there's been quite a few players in the past that have been restricted from playing the game for simply using this to troll other users. I just wish to point this out here so people do not get any ideas and end up getting themselves or others in trouble.
It's a bad thing to use chat glitches to ruin other peoples posts, just common sense not to.
