Microsoft acting as a censor?

One comment from this anti-DRM petition [1] says:
Oh and guys signing this petition.. try saying http://freethebbc.info on MSN - the message send will fail! Microsoft are filtering the website on UK MSN at least, so this has loads of attention ;-) keep signing!
Can please someone confirm this behaviour?

UPDATE: OK, seems that they "censor" everything that has .info and profile.php . How pathetic this "security measure" is?
