Don't let teroristes and dictators use social networks (Facebook, Twitter, etc. )

I am terribly shocked to find out that dictators and terrorists (such as Ali Khamenei - Iran’s leader) are authorized to use our social networks to spread hatred within people and spread fear and their evil ideas. 

Dictators and terrorists who massacre with no pity their own people, children and innocents and deprive them of their most basic freedoms; they use religion to their own benefits and enrichments, in order to stay in power.

Do you find it normal that we let these terrorists and dictators to use the technology and know-how of the "Westerners" to come to war against the same Westerners? That they use these networks to make a universal advertising and to find new members? They can be in direct contact with their little minded followers to get more powerful and organize other deadly attacks.

Please ask CEOs and other decision makers of Facebook, Twitter and other social networks not to authorize the terrorists and dictators to "USE" these technologies.
