Explain this about the random number generators

I would argue against this. Although it doesn't make a difference in what you should do because a random card is a random card, I'd rather play at a site that doesn't know what the turn is going to be until it deals the turn. IMO this makes it harder to be hacked. If the poker room doesn't know what card is coming next, a hacker can't know either. Of course if they've already hacked the site then they probably know your cards, but at least they don't get to know what's coming.

There has been a case where a pre-generated deck, combined with a bad RN generator, has led to an exploit (from the Zoo FAQ):

However, as a fallout of this incident, most sites have invested heavily in much more robust RNG, so the likelyhood of a pre-generated deck being exploitable is probably small.
