This is Bret Taylor, CTO of Facebook. I responded on the other thread (http://news.ycombinator.com/item?id=1932259), but cross-posting here since it is largely about the same issue.
This was a mistake on our part. In the process of dealing with a routine trademark violation issue regarding some links posted to Facebook, we inadvertently blocked all mentions of the phrase "lamebook" on Facebook. We are committed to promoting free expression on Facebook. We apologize for our mistake in this case, and we are working to fix the process that led to this happening.
