I had to laugh at Ghoste's dialog, it reminded me of an interaction I had with a kid a few weeks ago. At least I hope it was a kid!
I was soloing the Catacombs with my mid-level pally. I was in the middle of a fight and a join box pops up, I quickly hit decline and keep fighting. It pops again a few seconds later. I decline again, finish the fight then look up the name in the Who list to see if perhaps the guild would clue me in to whether I know this person. Nope - never heard of the toon or the guild.
About 20 minutes later, I get another invite along with a tell that says "Join!" I decline the invite and send a replay asking "Do I know you?" I get another invite and a reply "It doesn't matter, just Join! JOIN! JOIN! JOIN" I reply "It does matter - if I know you I will probably forgive you for the rudeness, if I don't, I am going to squelch and report you." That took care of it, no more invites, no more tells
It was a Sunday morning and there wasn't much going on. I did feel a little sorry for whoever it was, I could just picture some poor kid sitting at his computer thinking "I need a Paladin! I don't care what she's doing! I want her to JOIN!!!" Like the Borg....
