Oh, wow, that's too bad, because it probably means that your podficcing skills would be AMAZING. But yeah, this is something I have also thought about, since my profession is definitely one where I could be fired if I were linked to NC-17 podficcing (though my job doesn't use my recorded voice). I've personally found comfort with it by deciding my voice isn't unique enough—I've been mistaken for other readers, etc.—that I could have plausible deniability if someone confronted me saying "Is this reader you?" I could just be like, "Huh, nope. Bizarre coincidence, though!" And that's IF someone not only listened to my podfic, but listened to it far enough to get to the NC-17 stuff, which seems pretty unlikely if they're someone who is going to be scandalized and upset by it...

But everybody has different comfort levels, and differently unique voices, and it's *definitely* not worth it to cross a line that feels unsafe to you.
