No idea. We "optimised" for the new algo, and those sites who went down past update are up again, but we don’t know if they have undone the changes or is just that the new "optimisation", code word for easy silly spammy tricks, is working. We will be more than happy to take down those "optimisation" tricks, so we’ll try to find out.
Anyhow, I´ll said keyword proximity is back again, but dmoz weight and anti-bombing measures are still there.
