Surprisingly, no. Most sites do a good job of finding and banning bots.
It's also fairly easy to spot a bot. They will make odd sized bets at times. You check to see if that betting line is taken in a solver.
I'm sure there is some, but it's standard practice to keep at database of all your hands.
I've sanity checked the winning regs (at my stakes) and they all make mistakes.
I think it helps that in the US all the sites are geography based. It makes it harder and less financially viable to run a bot ring.

Even some people who are victims of scams admit that at the time they sent some/all of money they knew it was a scam but did it anyway.
