The crappy and super slow implementation of ECC arithmetic linked to on that website checks keys generated against a couple thousand 32 bit values. (Why use a slow thing like that if you've supposedly got some amazing gpu thing). My guess was that he's using this as bait to get people to run that program and the values that its looking for are all 'near' high value keys.

Or other wise it just another lame market manipulation attempt. Either way, ... if he actually can crack something I welcome him to go solve any of the 200,000 keys I listed and collect his bounty.

Thanks for decoding his JS, I'd just ignored it.
