I took a look,  at first glance I dislike such an idea. I think that simply a good set of categories freely classifying as many kinds of "offensive contents" as needed from endless list of personal idiosyncrasies coupled with some simple user-side js tool, freely built by user itself to "filter" images, should be sufficient. Users should be simply encouraged to add such categories to offending images, and to build filtering tools, by themselves or with some help from willing friends; problem solved, IMHO.

And - what about wikipedia, or sister projects, using "offensive images"? Is such a filtering procedure to be extended to articles using offensive images too into any wiki?
