Assume that, pursuant to my DMCA takedown request, an ISP takes down a page that contains content infringing upon my copyright. What's to prevent the infringing party from simply putting the same content up again as a new (different) page, with a new (different) URL?
And a corollary query: assuming that Google has de-indexed a certain page pursuant to my request, does Google have a mechanism that automatically detects the behavior described above to keep it out of its index?
And what about ISP? Its personnel certainly wouldn't continue to monitor an errant user's behavior, would they? So would it be up to me to go back to the site occasionally, check to see if infringing content has been put back up, and then issue another DMCA notice to the ISP, hoping that the second time the ISP will simply remove that user's account (and the infringer's entire site)?
