Doubt it, Twitter had that feature years ago and there wasn't a major problem that linked to it. Crazy people can't follow protocols, and most realizes they're in the wrong before blocking million accounts. References to useful contents from blocked accounts will occasionally leak through channels, and that should validate/invalidate choices. It's probably a pain for spammers and an extra processing cost for serving platform, though. edit: if you consider it must to block massive amount of real users(i.e. not script bots and/or third world hired guns trying to destroy a platform) to use a platform normally, that's just not sane.
