It's just bad play

[Maya]

I think the big number of bad beats is due to the big number of bad players (or bad play) on the site. When players view this as a free site that won’t cost them anything if they keep calling or chasing with absolutely nothing, they just do it. And they end up hitting miracles on the river that any average player would have folded before actually getting to see.
If I may quote @vtpcwizard on a similar issue, he said:

There are, admittedly, oodles of folks on the site that will stay for the river despite having a weak hand because they view the chips as “free” and almost worthless. When this is happening, you have a couple of choices. One, using patience and knowledge, await the opportunity to clean them out. Two, move up to a level where the “freeloaders” are less numerous and you’re playing folks that actually know the game and are working to improve their game and have some fun. This where diligent Bank Roll Management (BRM) comes into play and can provide you with games that challenge your skill level and lead to greater knowledge/success in the game. You might ask yourself what your motivation is in playing online Poker. Is it to win chips or is it to better your skill as a player? What are the metrics of your play history? There are plenty of games on RPP that might better fit your skill level and desires than the ones where you’re seeing ridiculous plays that happen to get lucky at the river just because they stuck it out against the “odds”. At the higher levels there is more “real” play. Give it a try.
