I dunno. I have a few and know of more sites with the same scenario - plenty of Wikipedia cites, entries in DMOZ, and thus heavily scraped, and none of them seem to be getting link notifications or being slapped (and I've asked) There must be a ginormous number of sites with the same circumstances. I just can't shake loose the thought that there's something else going on here.
Not that I'm a fan of Google's automated backlink policing - far from it. But the scenario being described here seems so silly that I think some caution is a good idea before settling on a conclusion.
