Syria blocks text messages (mobile.bloomberg.com)

I was one of the engineers who worked on SMS Defence between 2008 and early 2010. I wrote a lot of the filtering, monitoring and throttling code. We deployed it in Syria because a large percentage of their sms traffic was caused by a virus and they wanted a way to reduce this traffic (as well as other spam and preventing the spread of viruses).

Feel free to get in touch if anyone has any questions.
