Thanks for sharing the use case. However using it to defend the entire DMCA sounds like a false dichotomy. Surely there's a way to make rules only for those "awesome" uses, so that they don't have to be "clever" uses. C stands for Copyright and it's mainly used that way in practice.

I applaud you for using the DMCA for good. You're doing good work, and please keep doing that. That doesn't mean that the DMCA can't also be used for evil, though.

It would be nice if it could only be used for good, but maybe that's impossible. It may also be possible to replace it with something more specifically tailored to take down revenge porn. I certainly think revenge porn is far more serious than a mere copyright violation.

I don't really see how this is helping, you're just dragging your service down by getting it involved with this for no good reason.
