i don't think we have to implement such a feature.

1. it adds really a lot of overhead.
2. are we going to block ligal porno? :P hahaha
   if yes we simply need a plugin for snort to detect pink pixels

That would be a simple and effective way for a Tor2web operator to apply a content-policy, related to what represent a very specific high-risk-content causing takedowns.
Without having to apply any blocklist.

To be considered

fabio people than will start to go for black and white images or

That would be a very cool feature. Rather than blocking, we could just transform image into black and white ascii-art?

probably trying to transform audio in video and viceversa is a better
research topic.

I think this is a bad idea. We should not block content automatically - never !
