FoldBot is always on the play money tables. It is some times on the real money tables. But I haven't had the chance to see it on a real money table.
I saw it there once but another player was playing against it and I was lazy. So I entered, kept bluff raising and walked away with 34 more chips or something like that (at the river that other player finally folded).
I played that guy for awhile, still ended up with over 800 chips from him and FoldBot. I don't know if he was bluffing or got lazy.
