So, what, it's *simpler* to silently block them than to drop them a note saying "hey, this seems a little unusual. It looks like you're tunneling our side and adding advertisements to it, which isn't really cool. You're welcome to mirror the content, of course, but you should serve the pages from your own servers -- here's a link to the public database dumps and the software we use to run it -- but make sure also to include the appropriate information and backlinks to comply with the license.

I 100% agree with Brion about this friendly approach to problems like this. Maybe they just didn't think things through clearly; maybe they thought this was fine. Only if they decide to be mean to us, we can use technical means to stop this. Otherwise, we should try to keep friendly with people who are trying to reuse our content.
