The Saudi Arabian Communications and Information Technology Commission (CITC) studies ways to uncover social media users' real identities, according to a Friday report in daily newspaper Arab News Country’s Twitter microbloggers are top-priority candidates to get tokenized.

This could easily be accomplished by monitoring users who access Twitter from mobile phones, by requiring them to register an ID when they add money to their phone accounts.
