Banning Social Media – a good idea?

I am really against banning social media – especially with the reasoning of the work performance. To me, this is a management job, not a technology job and by banning social media to make people more productive – I doubt that this is really successful.

Now, I read this article: Why Banning Social Media Often Backfires which is definitely worth reading! as it goes down the road I just mentioned above.
