So, how about if the legislation required a DMCA adherence clause--that before a site could be taken down an official notice would need to be sent to administrative contact of the domain. If no official response is received in X days then the DOJ could issue a black listing. However, if the administrator does respond either by complying or by issuing a counter claim then the DOJ could not issue a black listing. The issue would have to be worked out the way DMCA conflicts are worked out. Now, should the initial DMCA take down notice be found to be legitimate and the site operator still does not comply in X days, then the DOJ may issue a black listing.
Would that resolve your concern?
