I realize that in general most cases of inactivity in a game are just the person joined then forgot, or something similar, and it's virtually impossible to prove otherwise, however, in this case...
Game 13306, from the in game chat:
2006-04-08 00:53:44 - SqueekyDragon: Alliance arranged between Sero and SqueekyDragon.
2006-04-08 00:57:58 - WittyName: deadbeat by WittyName, have fun boys
I realize there isn't a rule against this so far as I can tell, but...
Thoughts?
