I think the signal on 6230 is the same as the tone transmitter judging by the strength.
I think you both might be right, or near the truth. All I can say, judging briefly from the current content I listened to, is that it is currently transmitting a religious speech in Arabic (not Persian) and I hear Arabic words and phrases suggesting it is about religious Shia Islam places in Iraq. I have some elementary Arabic language knowledge
It seems way too strong to be pirate, but it may be clandestine in the sense that it doesn't officially have permission to be on 6230 khz.
There has been a lot of unrest in Shia dominated Iraq... and also of course in Iran with the petrol protests.... and the fact that they cut off internet access, means that shortwave is used to circumvent internet blockades by some religious group in the middle east?
