How gullible and naiive are you to think it's rigged :)
Studies show that in the Bot v Player race, the player wins in the long run as the Bot makes the same decisions in the same places so can easily be played against. In depth scientific studies with the most advanced bots in the world showed this. It was even an article here on the register. So even if one bot is sat at the table, you'll only lose if you're bad player (in which you'd lose anyway....)
As for "random". The sites are Governed and ensured that the algorithms indeed are completely random. There is no way anyone can disagree with that comment. A lot of people have a bad run at a site and think its purposly rigged, but what would the Poker Room's have to gain from that? They take money in the form of a rake so they want it nice and fair of course... Use some logic and try not call other people naiive just because you don't understand it!
As for slot machines... That is a pure random luck game. Poker (Especially texas hold'em) has much more skill due to the reading of betting patterns and the mathematics of the game including equity, pot odds, implied odds, etc.... Once again if you don't know what these mean, you can't really argue about it...
Online Poker has always been a fair and fun way of getting on the tables, on the internet... The ONLY danger is collusion. Methods such as monitoring IP Addresses help to get around collusion, but with a whole botnet doing it, that's the worrying thing. However, I'm still rather sure that this is an incredibly rare occurance.
