I was getting 2-3 invites a day from them, which tended to kick me out of full-screen games whenever I was playing them when the invite came. I never recognized anybody in the room, and had no idea how my name had been added to this guy's list of random invitees. I finally resolved the issue by being uncharacteristically rude, telling dead baby jokes and such, at which point they told me that there were rules and that I must follow them. Said rules were never articulated, but I was soon asked to leave, and with a merry /finger, parted the channel and have never again received another invitation.

Yeah I've gotten two already from this person. I'm not sure who they are, but they didn't say much other than the two invites and something about dumperscoots playclub. I googled some stuff but this is all I really got:

Anyway yeah D: No idea!

Based on the short time I was in the room, that seems to fit. Just call random people, drop them into a room, then watch as chaos ensues.

I've blocked him since then. No problems since.
