Google Big Daddy update sucks

G seems to be updating its index for the last few weeks. With the new upf=dates, they've finally fixed couple of the commands. However, they seems to have majorly screwed up their indexing. Peole are complaining that that quite a few spam sites that were originally dropped from the G index are now back in. Not only that but the doorways seems to be back in fashion with the new update. I don't believe this is intentional but G somehow has made a big mistake somewhere.
