Well, that's debatable. The mosaic law did provide for the stoning of adulterers, didn't it? But Christ did away with that poriton of the mosaic law. Nowadays, if you go see the Bishop about adultery he's not going to take a rock out of his desk and throw it at you.
And I guess that a porn producer is not technically engaged in the act of adultery himself, at least, not necessarily.
But still, it's a vile and horrible thing to do.

I wouldn't call it spiritual suicide. Suicide is, after all, pretty much a one way trip. You aren't going to live again until the resurrection. Spiritual suicide would be an act that you couldn't recover from spiritually. A porn producer could repent. But I imagine it would be extremely hard. He'd have to have a whole attitude, career, and lifestyle change.

Muslim governments seem to impose overly harsh punishments in general. I probably wouldn't classify porn production as a capital offense.

But the world would be a better place if governments around the world viewed pornographers closer to the way the Iranian government views them than how western governments view them. (Porn producers almost seem to be a privileged occupation here because their products are "speech" which must be protected at all costs.)

The thing that disturbs me is the open-ended definition of porn. They could define it as something as innocuous as a picture of a woman with her burqa pulled up over her knees. Stuff like that makes the whole 'freedom of speech' issue come to mind. No we don't like true porn. But for true freedom to protest things we feel are wrong and giving other people the same freedom, we have to be very liberal (if you'll excuse the word) in our allowances. I mean, we teach correct principles and let the people govern themselves, right? If the people are righteous, they won't produce porn no matter what the law says. If people are evil, they will produce porn no matter what the law says (though admittedly less so with the fear of being caught under such harsh laws).

I hate porn. I really do. But I don't think such a harsh law using such an ambiguous definition of porn is the answer.

Sounds a bit severe for the adult Porn folks. I would definitely support it for anyone making, distributing, purchasing, or watching child porn.
