the adsense program has probably been THE major contributor

SE spammers were already building the massive throw away sites well before Adsense. Any efficient monetization program would have had the same effect of increasing the quantity of those types of sites. (Regardless of whether it was Google's program or not.)

Point in case, the MFA sites are as much a problem for Yahoo and MSN (if not more so) then they are for Google.
