Unfortunately, it is often one of the copiers that will be found first, which is especially a problem if one does not get the same one every time.

This is a direct consequence of producing "free" content that can be copied to any URL. Every copy is a kind of fork, since it isn't automatically updated when the source is updated (and vice versa), and since the readership is split between the various site owners. If copying is unfortunate, then "free" contents is the wrong method. But I think the consensus is that "free is right" and thus copying, duplication and forking must be good.

Perhaps Google is the problem, since it points to websites (providers) and not to contents. It recognizes that two pages are on the same site, but it is not nearly as good to recognize that two pages have the same contents.
