Like everyone else who's posted in this thread, I too have ran into individuals as such.
I remember one time when I was on Bane Hollow (old character) and I was lurking around in Bonfire. I so happened to spot another character (won't say names) all of a sudden claiming the top of the TLK den as her territory and nobody else's. Curious, and deciding to be a pest, I generally got up and hopped my way up to her just to sit down and watch her chase off all the little floofs. Of course, I took screenshots. Well, then she decided to threaten me and god-mod me. Even still, I didn't move. Only then did I move when she decided to butt-swing/head-bang over me. I screenshoted the whole ordeal first before moving to report her. I'll never forget that incident just by how amusing it was.
