Kuwait Deporting Immigrants If they use Viber, Skype etc

Kuwait authorities are deporting immigrants if they are caught using voip services such as Viber, Skype, Tango and other similar services.
My friend was removing/reinstalling Viber again and again i asked the reason. She told that Viber is not allowed in Kuwait.
Kuwait says using voip services is illegal. They are trying to catch people who are still using them.
