Facebook is signing its own death warrant
Here's an experiment I just did following a comment to the effect Facebook were censoring threads by a close relative. It's an experiment which any Facebook user can easily repeat. Start a Facebook thread with a number of quotes, including from Shakespeare, Bob Dylan, Bill Gates etc. and see which of these get deleted by Facebook. In my case I posted a single verse and chorus lyric from Mr Tambourine Man, and Facebook software deleted it, despite the fact that within the thread context this was clearly fair use. Facebook can only be trusted as a neutral message boy if they don't fuck with our communications by opening messages and throwing stuff away arbitrarily.
