Also, on a related tangent if anyone's interested, how it works on SM is you get 10 mins. If your stream then auto-connects and no one is there, the stream is ended. You don't get in trouble for it or anything, you just get a message basically saying; "we saw no one was on your stream, so it's been ended. Reconnect when you're ready." If you want to return sooner than the 10, you are able to anytime you hit the button to end your break.
There are times I have to use it to let my dog out real quick, and don't need a full ten mins.
Most of the time, I end my stream after a show, rather than use it.
But I could see on token sites how that would suck.
I have no clue the specifics of how it works on any other site, never paid close enough attention anywhere else.
