Just replying as I read 'em, so forgive if I haven't reached the reply yet. ;)

Steve (and Fencer, too)(: Some pawns are pawns because they only get to play now and then at the library or somesuch, and purposely set their moves to the max time limit in case they can't make it before then. (I know of one case quite personally, as I won't let her touch my machine. ;)

RogueLion: This is a good point. Anti-backgammon games, for instance. I've had some go on for over a year (at another site), and even then only finished because of a timeout. :/

Interjection to conversation: Personally I'm not sure I like the idea of BKR decay at all, as it will likely not affect the abusers at all. Like spammers, they'll just find ways around the gates. That said, what if only game types where none were in progress -and- none had been finished in the past, say, 90 days had the BKR affected?
