The DMCA is broad enough that posting a link may be considered "aiding" copyright infringement (that's a stretch, but since they hold the weapons, your shields need to be stronger). If all you do is post links to sites, then you have a legitimate claim that all you're doing is providing examples (and this is covered under fair use).

But if you do intend on fighting it calling it BS, your alternative is to file a counter-claim. Going against BS takes effort, as they say.
