I bought a cd set from digital automation 2000 off eBay. I was surprised to see hundreds of scanned plans from RCM, MAN, MA and many others. I looked up the tortuous way to protest to eBay officials, filed negative feedback on the seller, and called and talked to RCM and MAN. I offerd the original cds so they could prosecute.
The seller replied in his answer to my negative feedback that the scanned images were provided for my viewing only, so no infringement occured. EBay accepted this and no one took action. I know some of the designers who had plans copied, and they say that practice takes money out of their pockets. RCM and MAN sadi they would contact eBay to complain. Shortly thereafter, the seller, who had been around for years, went away. Several months later, another seller appeared hawking very similar cds using the same language in the ads as digital automation.
It is possible to get eBay to act. That needs to come from someone with clout. Unfortunately, the offenders pop back up like the vermin they are.
BTW, I also bought from uncle willy. I guess I am part of the problem, but you don't know who the offenders are until you buy, unless forums such as this expose them. They will still stay in business because you can't reach all the potential buyers and most of them do not care.
end of rant
Take care.
