I'm not sure if it's in some way "unfair" or not. One thing would be that his negative results aren't published whereas PRPnet's are. But unless he has serious computational power the few negatives he produces wouldn't have helped PRPnet that much.
If he works fully independent, I'd have no problem, after all nobody owns Factorials, but if he uses PRPnet to some extent - and him being that close to the edge make it seem like it - that would be like poaching. Does anyone know if he's involved somewhere like Mersenneforum?
