The DMCA has certain requirements about taking stuff down in response to a claim. There is also a provision for restoring content in the event of a counterclaim. All of this was designed in the context of copyright infringement by a third party, while you are have an (alleged) circumvention device and are self-hosting, so I'm not sure how that would apply. In any event, you should consider taking content down (including wiki history etc) until you have received legal advice. It would suck if you were ultimately in a position to prevail, but ended up in trouble over procedural technicalities. IANAL (or even in the US!), etc.
