2011 Poster Of The Year
He can just change his twitter handle, it doesn't require him to start a "new" Twitter. Hell, Morrison still uses his Twitter with WWE logo and everything. He won't lose followers unless they unfollow him...which is highly unlikely to get a mass exodus of unfollowing on Twitter. FWIW, Morrison has a little under 600K followers.
The facebook like-page (facebook is becoming archaic, really) is a grey area, as most of those are corporate run. But Twitter accounts are run completely by the talent, and by all accounts are owned and operated by the talent themselves.
Just did some random investigating, and it looks like the twitter thing is hit or miss. A lot of guys using the same one (like Morrison), and some other old WWE ones appear to be deleted. Could be that the talent deleted the old ones, but why on earth would you do that if you didn't have to? Makes no sense to me, but who knows.
