Ummmmmm......
WHAT THE FREAK IS NOT TO LIKE ABOUT 420!!!!
I have this happen allot, even when I'm not being edgy with my words. Like you cant say hell or fart (this one may have changed) or........ I don't know, there is a bunch that are not bad words, but it still draws a mute. Maybe a "Rated G" version of a dictionary should be posted of "misdemeanor word's of world chat" to help us bad bad bad people, that say them. So we can grow as individual's in a more healthy gaming inviroment.....?
Or it really could be some "HIGH" and mighty, hall monitor tyep. That is afraid to talk to you because they get all goofy around HOT CHICKS, so they find it easier to just mute you then, feel awkward over their own personal inadequacy. You know, "boy likes girl so punchies her".... Lol just a guess, hope it helps!!!
