According to Wired’s Danger Room:
The Air Force is tightening restrictions on which blogs its troops can read, cutting off access to just about any independent site with the word “blog” in its web address.This includes all websites with a “blogspot” U.R.L. unless specifically exempted from the filter.
I’ve also had difficulty sending emails that include the term “blogspot” to folks at Harvard. There the problem seems to be an overeager spam filter.
The term “Revolutionary” doesn’t seem to bother either institution’s software.
