To tell you honestly, online poker cheats exist and nowadays, people playing in every poker sites today make no mistake. However, the nature of the cheating that takes place in online poker is very different from what many might imagine, and is far less sinister.
Like some online casino, the cheats in poker rooms including the poker bots that are playing against you and other real opponents and defeating all of you with the best artificial poker intelligence where the poker bots able to see your cards; players able to see the cards on the poker room's server; and players employed by the poker room to beat "normal" honest players. All of that is sheer nonsense and simply does not happen.
