Major League Baseball bans MLB.com writers from using Twitter for non-baseball topics

Multiple sources have confirmed to me that Major League Baseball is cracking down on Twitter usage, ordering MLB.com writers to cease tweeting about all non-baseball topics and scolding players for their Twitter usage in general. As someone who has every MLB.com beat writer and several MLB players in my Twitter feed, this is very unfortunate and strikes me as a massive overreaction. Allowing the writers and players to show a bit of personality and interact with fans/readers was a positive thing and certainly caused me to become a fan of those who did it well. Certainly setting standards for the type of content MLB employees post on Twitter is reasonable, but simply banning all non-baseball talk for MLB.com writers and preemptively scolding players who’ve done nothing wrong is ... well, it’s just a real shame. I’m told a big part of the policy change is due to MLB not wanting non-baseball tweets showing up on the MLB.com Twitter feed/aggregator, but banning every writer from non-baseball talk because of that is like killing a fly with a sledgehammer. UPDATE: MLB denies Twitter crackdown, but facts say otherwise
