A site-wide 301 in most cases results in a -50 "goog full of paranoia" penalty. At least it raises a flag and the website will be inspected by a manual Goog owned and underpaid Indian or whatever pest inspector.
Don't do this with two domains at the same time (footprint), they will kick your ass (I mean the pest inspector will kick your ass) if you try this, you wil find yourself in the -50 hell with all your domains in your webmaster tools account. Warning! Even domains which did no 301 redirect will be send to -50 hell!
They need to do this because a 301 will NEVER transfer the original penalty. (reason: dumb algo which means dumb people, dumb goog engineers)
Believe me, this is 100% experience based, no conspiracy theory, this is fact!
How many slave spies from Goog are reading this? I believe at least a dozen. They all want to earn more money and will report back to the Goog Gods.
