Are you a library that has gotten one of the cut-n-paste emails warning about “hardcore and even child porn” images on Flickr? Do you host a library-oriented group that has suddenly had an inundation of inappropriate (and possibly pornographic) pictures from users unknown to you? If so, you are not alone. Libraries and librarians have set up a discussion forum in this Flickr group to talk tactics. Michael Stephens has some backstory about the problem on ALA TechSource, particularly concerning as we watch DOPA inexorably move through Congress.
Educate your users—your community—about the good and bad of social software. I’d much rather give a roadmap and some guidance to someone instead of blocking access.
