anything short of he himself announcing he was a fraud that would change your belief. Were I you, I would not bother reading anything except JONP.
If Rossi announces himself a fraud, it would be considered a clever action to avoid too much attention before he can ramp up production. That is what was said about why his SK "industrialization" presentation was so amateurish. And also ECW is a safe zone that Mark can read as well as JONP and even Reseach Gate, if you only stick to the paper with the highest "full reads".
