Yeah, I do recall people doing these things. Even people from the roleplay I'm in.
I remember 'Snow Queen', she was by the Cape Portal.
Though, I didn't take it as 'get lost' or anything, I simply played along in my own way. ^^
Oh, I hate claimers.
Once, on my Warrior, GrimmStar, I was in my own territory, not claiming a thing, but then another clan, two to be exact come say: "What are you doing on MY HighRock?"
or:
"You're too close to our territory!"
I'm not even near a territory, this stuff just seriously annoys me sometimes.
