Big winners on Crypto--single deck black jack?

[spikeanut]

Just curious if anyone knows about the players who constantly keep showing up on the weekly big winner charts, solely on the single deck BJ. For instance, if you check, there's this player, clayton1, who appears 3/5 times as having the biggest wins for week, from 13000 to 29000, all on single deck blackjack. Just wondering how people are accomplishing this?
