If SOPA/PIPA passes, and some content creator (Ubisoft) decides that mods are infringements of their copyright on Silent Hunter, is it possible that Subsim could be a target of a cease and desist? Shut down even?

It certainly seems like it would run afoul of the part where a site could be nailed it it were "primarily as a means for engaging in, enabling, or facilitating the activities" of copyright infringement or counterfeit products; or if the site is designed by its operator "as a means for engaging in, enabling, or facilitating the activities" of copyright infringement or counterfeit products.
