After all, it's so incredibly easy to find the sherrithing, too - as 'she' has splashed 'her' name all over the Net! - that if the Iranian mullahs did not like what 'she' was vomiting forth, they'd have had no trouble shutting that malignant maw....... They've done it to others, after all.
Maybe it's not a formal arrangement, 'Rock - but I expect 'the authorities' are aware of the sherriliar's stint as a useful idiot, and they approve.
We can at least hope that these performances here are buying some folks 'back home' a bit better treatment form the regime that's helped to murder over 100,000 Syrian civilians, and sent millions fleeing to uncertain futures : ))
