Tousi is a known MI-5 asset. Those 700 arrested in Iran are people who were in contact with the known saboteurs apprehended by the intelligence apparatus via electronic surveillance.
Its the same MO as in the west or any other country.
If some one is evidently anti state, or anybody who comes into contact with that person, comes under surveillance.
This is what I told Doc the other day is what is happening on Irani/ Zoro forums. If you don't keep a balance between the Persian Jews/ Shahi's/ Khans of Tehran/ MEK operatives/ Zabardasti k khoshamdi/ Muzlim incensed jihadi converts/ Unwanted Christy X-Tian (evangelicals)/ and lets not forget 'Born again Iranians from Central Haitia/ Afghani'.....Die hard ex-Sovietized communist sympathizers cuz Iran's fighting the west....you start getting mysterious phone calls and unwanted solicitations meeting strange people........seeing things.....intense online abuse....
Its really not worth running Irani forum because of the seriously charged environment.
