Issue number 1 isn't really an issue. Don't worry about it. If it makes the others (usually live ones) in the game uncomfortable (which occasionally happens), politely ask them to play the hand out. Usually, though, don't worry about it.

Issue number 2 is something that you won't see anyway. Collusion of this nature isn't an issue in most games. If things don't feel "right" then quit. That's your only recourse.
