Because the original is penalized and this one hasn't yet.
I'm worrying because it's 7th month after the first Panda without significant recovery for me except a small improvement on Sept 28th, and without penalization of these MFAs.
The only thing that left unchanged on my cleaned-up site are these non-adsense ads. I think I'll remove 2 out of 3 of these units (and halve my income, but if I recover Google traffic I'll be in plus after all.)
