Iran Stoning: What's Going On?

The reporting of the apparent case of two young Iranian men sentenced to death by stoning for allegedly raping a male youth has often been predictably unreliable (though noticably more cautious than before) - with some gay media playing down the rape charge.
Towleroad framed their report as 'Iranian Men to be Stoned to Death for Gay Sex'
But the charge is not "gay sex", it is "male rape" [This page has been deleted by Towleroad].
On Gay Middle East Paul Canning and Dan Littauer try and sift through the hysteria, stupid cliches and propaganda to find out what we can know - and explain why we can know so little; it is not even 100% certain that the case actually exists.
How can we be sure of anything about a case when we do not even know the mens' names?
Canning and Littauer note a Catch 22 in Iranian prosecutions for homosexual acts;
"As noted yesterday, the Iranian government, as reported by Human Rights Watch, maintains in response to international pressure regarding reported executions of homosexuals that they mostly involve “individuals [who] have been charged for forcible sodomy or rape”.
"But as noted yesterday by Soheila Vahdati, an independent human rights defender based in San Francisco: “They [the Iranian government] don’t differentiate between rape and homosexual acts."
And furthermore, they quote Hossein Alizadeh, Regional Coordinator for IGLHRC’s Middle East and North Africa Program;
“Iran has an impenetrable and opaque criminal justice system that makes knowing what is really happening inside the country impossible.”
One thing does seem grimly certain and undisputed;
"At this stage it is, however, believed that all sources concur on the fact of a death sentence."
A great crime.
