Strange that they're blocking software rather than websites. E.g. the github block says "gist-it" next to it, which implies they maybe wanted to block https://github.com/robertkrimen/gist-it ? There's also http://atnsoft.com/atnsoft.com/textpaster/ blocked and http://sourceforge.net/projects/phorkie/ which is described as "Self-hosted pastebin software written in PHP. Pastes are editable, may have multiple files and are stored in git repositories." Which is really strange because it says there were only 4 downloads of this software in the last week -- doesn't that make it easier to track?
