No, because they are provably fair. If you think they are rigging bets there are things you can do to make it impossible for them to do so in the dark. Of course they can always steal from you once, but at least you'd have proof of it. Of all the accusations I've seen, I've only heard "20 in a row!!!" (statistically possible) and the like.
If you don't use those checks and balances to be sure you aren't being had, well that's on you. The table has always been against you loosing though, you've never had the chance, no matter how slight, of coming out ahead after many bets. Placing more bets just gives variance more of a chance to screw you, as it is supposed to.
Okay... so this was my epiphany; why are you trying to rain on my enlightenment? Here's my emoticon with X's for eyes and the tongue sticking out just for you: xx-P
But on a serious note, what are the checks and balances? Changing the client seed that can be changed by a quick hiccup on the server side? I've done that just to check my proof and it wasn't what I entered. I understand losing and odds - I certainly don't expect to win 1/2 of the time even playing 50/50. But what I do expect is to be given the fair chance - the odds I pay for.
Besides, the issue isn't the fact that I'm being had, the point is it's getting hard to find a casino where you won't be had. Perceived or real had. We wouldn't need those precautions if the 'had' don't exist, right?
Because for every post like yours I see, the guy making it really doesn't see the issue. I've tried pointing it out before, but it never seems to work. I'm not trying to rain on any enlightenment, just make my point that you were never in a situation to come out ahead, the odds were always against you. I'm not sure if you see that now, but it would probably be a good thing to know. Hope you don't get mad that I thought I'd point that out for your benefit.
You are making a claim that a popular site is ripping you off, yet you don't have any proof. If you have proof that a roll should have been a winning bet, but it came up loosing, you'd have a case. Either you don't know how to check them properly, or you actually have proof. If you were to continue using these sites I imagine such a skill would be most beneficial to learn. Confirm that you were ripped off and make it public (best be sure though, I don't like to look foolish any more than I have to myself.)
All casinos are set up to take from you, please learn that now. Even the "fair" ones, they all have a house edge. You might win, but the thing is you don't complain then. When the odds go against you, all the sudden it's "fixed!"
Can't you see that madness?
