I don't remember if there was an announcement as to exactly why but I am pretty sure Gridle was tired of moderating it (he was the only mod), it was redundant, the host kept going down, and it was pretty much a stain of Moogly Guy flames in the end. I've never seen anyone get away with as much murder on a messageboard as he did on mame.net in its final year. He lit every newbie on fire and Gridle just sat there eating Doritos.
