Yeah, I've been in a few group games on other sites where it was like that.  Thankfully most of the ones I've done, or run, there is kind of a unwritten agreement to carry on no matter what.  The first game I ended up GMing on RPOL was this huge fantasy game that I'd worked my very psychotic elf up to power and the GM basically gave me full control over things.  And before my hiatus I gave over my quasi-Fables game over to players on that site.
