Lately I'm seeing numerous players who enjoy making a scene during group storylines and such. I am also certain some guilds do not want bad reputations because of their guild members behaving like trolls in the most obnoxious ways disturbing other players during their sessions.
You can't have a mature guild if some of your members are behaving so immaturely. I find this posting to be more helpful for players who wish not to get involve with these stereotypes. Posting names of the player avatars or their acct names (use of ignore blocks their acct so you see the name).
