Im seeing very strange results on yahoo. We were 1st for our major terms and now we are 90th with everyone that was top 10 in worse posistions then us. Above us are just spam results.

I am wondering if this is just some kind of huge spam attack on the yahoo search, or if its yahoo updating its algo, and in the middle these results would come through then go to their new results?

Any ideas?

Yahoo is such a crappy search engine. How do you tell when there are more spammy results than usual....
