Cheaters At Online Poker

Do you guys think there are a lot of cheaters at the lower level Hold Em Games? I have read articles about programs that allow you to see your opponent's cards and even programs that tell you the cards that are most likely to come up on the flop/turn/river. I have to wonder if someone is using these tools when I get my AA cracked by some guy calling a PF raise w/ T5s, then chasing a flush down on the river facing 2 pot-sized bets. I know that it would make more sense for cheaters to play at higher levels but at the lower levels it would probably be easier to get away with. Noone would suspect it and you could still make a killing. Are there many cheaters at the lower levels or are these donkeys just that BAD? I'm thinking they're just that bad but sometimes when a guy makes a few plays like this it makes me wonder.
