I have seen many scripts,e-books in bulk and such being sold on ebay that violate copyrights and then there are some that act as resellers for books of authors that don't categorically mention whether you can put a price tag to their e-books while distributing them or do it give it away for free.The copyright for some is still a gray zone , but then personally I do respect the copyrights and prefer to buy from people who fall under the same category.
