Information is a dangerous good
Flow of information is the key to control.
I guess that Spain needs to get a hold on facebook, twitter, snapchat, <whatever communication> domains too. Hell, while they are at it, they should shut down the internet and power too. Forbid books, pen and paper. Forbid verbal and non-verbal communication in the process too.
The lesson from history is that any action creates a reaction. And, unlike mother nature, the reaction is often much stronger than the action. Spain has, apparently, not yet learned that lesson well enough.
