Blitz format is reasonably popular on KGS (once you get to a certain level) usually 10+0. Blitz is harder to find on Pandanet - but you can easily blitz on Fox.
Zero increment blitz go is a terrible idea IMX; people will just play nonsense moves after the game should be ended, and calling a moderator takes time. Go lacks the absolute nature of checkmate.
http://online-go.com has an interesting anti-stalling feature: If you pass several times it checks with KataGo. If KataGo is 99% sure you will win, either player can click a button to accept that result and end the game.
