No, but it’s my understanding that you can copyright a collection of them if the act of doing so involved considerable work, as pointed out by warp and myself multiple times. So the original website that was scraped holds such a copyright. Please don’t express your opinion as a fact… Of course, IANAL and don’t play one on TV, so both sides could be argued in court. But the original poster doesn’t have any more rights in the data itself than the person who allegedly ripped him off. He has rights in his code, his database schema, etc., but not in the data itself.
