I agree that a redirected link sounds more secure. But the copying of your affiliate link into an Ebay owned page is remote, it happens, obviously but it is remote. So, a right click prevent would be easier to code and not add any processing overhead. Yes, it could be defeated, but it does make a remote occurrence even more remote.

It's better than doing nothing.

Actually, the answer to the problem is for Ebay to filter the content of it's blog, auctions and forums to prevent the posting of any "rover" URL. That's by far the easiest most secure way to do this. But they don't seem so inclined.
