Internet content filtering is the new book banning. My local library filters Hackaday, and lots of other innocuous things. The excuse for banning Hackaday is that it is allegedly a "hacking" website. The content filter is one of those canned IT solutions that governments love to patronize. It's here to keep The Children safe, and because vagrants would obviously come to the library and masturbate if there were no content filter. I guess it works because I've never seen a vagrant masturbating in the library. There is no person at the library who has any direct control over the unbanning of content. Anyone may submit a link to be banned for any reason and it will probably be banned. Getting a ban removed is a more complicated process. I find it ironic that even among librarians who think book banning is abhorrent, there are some who do not bat an eye at their Internet content filter.
