IANAL either, but the DMCA has been used (by the RIAA, MPAA, and friends) to takedown pirate content on Google. I’d assume the same arguments would apply here. It can’t hurt to try.
Linking to a site that infringes copyrights may make the linker liable on the grounds that they are committing contributory copyright infringement. It's cheaper for search engines to delist sites than fight that battle--particularly if their corporate masters also rely on licensing media for distribution themselves.
