IDK, you'd have to ask Jen for updates.
Nothing a spectator does could be so heinous that it can not be stopped by kicking them from your table - and nothing they do preclude us from having the option to hear our friends. I mean are we talking about some exorcist level verbal bile and gore being spewed all over our tables? If so, I don't think the admins would be so secretive, they'd just say "Okay guys, some people have been VERY naughty. Much like in the General Messages, spectator chat is now temporarily blocked."
And nothing,
nothing can be gained by autostart, except my neighbors were introduced to some new words and concepts every time it happens. You either start the actual game without asking if everyone's ready, so no fancy OK button (I mean if you're policing us that bad why ask permission afterwards), or you do nothing. Now you send us into limbo where we can't do anything, and the site freezes, all because you weren't quick enough to add someone who (despite all the obstacles) managed to convey that they wanted to join your table in the half-second it took for some guy to jump in.
Yes I've stated my case before. But what could be going on that is so bad, that they had to resort to this?
