Why you even making this thread if someone is really being offensive call a gm and they will act if they are really harrishing you or just /blacklisting them.
As for soloer or groups stealing mob this is an mmo and claiming and keeping mobs claimed is part of the game the fact people can steal your stuff may be offensive to you when really it's just them playing the game (while yea it's not nice) and if you have a issue w/ that then complain to SE cause they can easily make it so you can't lose claim and if ya wipe a mob depops.
