^ I also </3!
I haven't run into a lot of those, but one where I did, the entire party got majorly annoyed. We were AoEing in the 5x abyss with the guy tailing along, apparently in the bathroom for 15 minutes. When we banned him from the party, he immediately said "I'm back!" Our tank got so angry she went over and just started hitting him LOL. I'm just glad he learnt his lesson and just teleported xD If he started to rant, I bet that our party would track him down from and kill him another time once we see him HAHAA.
Anyways, I hate those guys. Taking advantage of others and using trickery to do so too >:
