Rp groups will be RP groups and you know this, instead of being a jerk yourself and running in messing with them, just ignore them and only pay attention to your friends chat etc.
These maps were made for everyone so, EVERYONE will do as they please until blocked, reported, ignored etc.
Like, once i was just with my friend rping, we walked into a cave to do a little rp, and yet their was another rp group there. For once, this group didnt mind us, so we just rped as they did, no harm done.
But remember half of the people playing this game are made of Younger children and Smart "ass" people. (Pardon my lang) But yea, if one cannot deal with it, why do you play?
One hope for furture patches is a Filter button for lang.
People will be people End of story.
