I find it very funny, how these double spenders make a brand new Bitcointalk account and complain how they weren't paid.

They also should realize that unless they use a completely new wallet, its very easy to track a given wallet just by looking at the change addresses. Just because your bet comes from a new bitcoin address, doesn't mean there isn't a trail with your other previously used addresses.

That's why I find it pretty surprisingly why they even bother going on those forum and complaining after they got caught trying to steal.
