I think it would be a little bit naive to trust all
online poker sites. There are always going to be some shady players and operators when there is money on the line.
Just look at the stock market or politics or anything that involves money or power.
But do I think there is any widespread "conspiracy" to rig the deck against us at most online poker rooms? No.
One of the biggest reasons why is because they already make hundreds of millions of dollars every year in rake. Why on earth would they want to risk that by doing anything shady?
Also, while there are plenty of "claims" of rigging out there, usually by disgruntled players who want to blame their losses on something, there has been no statistically significant evidence presented to prove this.
Until actual evidence is presented that involves sample sizes in the millions of
hands showing widespread statistical anomalies, it will just remain speculation on the internet.
FWIW, as somebody who has actually played 10+ million hands of
poker online, I have run the data myself in PokerTracker and I have not found any reason to conclude that there are any large irregularities in the RNG at any of the major online poker rooms.
Anyways, I discussed all this more in a recent YouTube video, why people think it is rigged and so on.
