The idea somone has to pay a third party to find the link to the WIKI article violates the copyright.
I don't think it does. I think eBay's reasons for closing the auction might be more pragmatic - but I can only guess as to their motives. Just because something is legal - does not mean it is necessarily a good thing (for eBay or us).
About Copyrights
I'm a published author - both in words and running code. No, really - hit Google for my name and email address - you'll see what I mean. I can write an article that refers to, describes, paraphrases or links to your article (perhaps it appears in the bibliography of my article). Unless I
COPY your article, I am not encroaching your copyright.
In fact, most authors like this. Your copyright does not prevent me from having my own copyright (and vice-versa). I may choose to charge for the work I created (or release it under a CC or GPL like license as you have done) - even if it refers to something done by you.
To actually see the work you created, they would have to click through that link or look up the citation in a library catalog. If linking to copyrighted material were illegal (or required every linked item to be checked for a suitable "link friendly" license) - Google and Yahoo! would be out of business (and so would most of the linked content of every Wiki on the planet).
Why do we tolerate linking, cataloging and indexing copyrighted material? Easy - so we can find it! What's the point of publishing something if no one can find it.
Standard disclaimer: I'm not a lawyer.
This person is (or was) providing a service - an incredibly trivial one but - I think - a legal one. It's a bit like publishing a phone book with only one phone number in it. Some people think valet parking is a waste of money. The buyer decides what is worthy of their money and what isn't.
