Heh, I think everyone knew it was going on but quite amusing to have one of the part-takers blow the whistle in such a fashion.
We had a Apprime planet exile into our gal earlier in the round. Someone's 'son'. Who never logged onto irc or even attacked. Just seemed to randomly send defence.
I don't think we can blame the MH's for this, it seems pretty impossible to stop/prove.
Just another stark reminder of how behind the times, open to exploitation, and generally crap this game is now.
