Robert Sciglimpaglia is the only guy I know with a name harder to spell than mine.
He’s also a practicing attorney as well as a seasoned voice-actor.
His compelling argument against a (ahem) certain P2P site is the kind of stuff that belongs in a voice-over primer (if there was one).
You can find his article almost everywhere today, but I’ll recommend you go to John Florian’s VoiceOverXtra to read it.
BTW, he doesn’t name the service he dissects, but I will: VOICEJOCKEYS.com
