Okay, I'm not rewriting my posts from the previous "rigged" thread, but anyone willing to claim that online poker is rigged, read this:

Okay, now that you've read why rigging an RNG is nigh impossible to do, let's go with the final argument of why it isn't done:
Obviously, it would be possible to rig single cases of RNG results. Those would not be statistically significant at all. Rigging one hand would surely go undetected. However, there does not seem to be a way for a poker site to gain any significant revenue from that. The idea is that instead, they rig the RNG so that "action hands" appear more often.
Now, let's assume for a moment that rigging a small amount of hands is possible to do undetected. They cannot rig a large sample since it would be provable with datamining, so they opt to rig a small sample instead.
The question is, will they be willing to do that? Let's forego all moral reasons, the fear of exposure when eg. some former employee spills such info. Let's just take into account the economical reasons.
The answer is, they won't do it because it simply is not profitable. The problem is, if you want to generate added revenue based on the "action hands", the sample has to be statistically significant. To rig a statistically significant sample even slightly, you require huge computational power, for the reasons described in my abovementioned 3 posts. This computational power would be at least
100 times more than the power needed to run the poker site itself. Imagine: for every server dedicated to running the site, 100 servers dedicated to rigging the resullts. Also, the algorithms required to do such corrections on the fly would make Google search algorithms pale in comparison.
So, dear rigged theorists, the answer to your questions is simple. The pokersites don't rig the RNG not necessarily because they're so moral or because they fear detection. They don't do it because, even if they wanted to do it, it simply costs too much.
