That is exactly what is happening to both of us
my pages are still in the index, they just are not showing in the SERP's.
I went from 25000 referrals from Yahoo the first 3 weeks of last month, to none. The only traffic I'm getting from them now is from overture.
I'm fairly sure we've been banned, I just don't have any idea why.
Yes achonister I am seeing the same thing. Pages still show up if I do a site:jacksretail.com yet searches turn up nothing not even on the last page.
I did find out one of the links to my site was one of those redirect/jump links. Is it possible this is what's causing it? There seems to be a lot of talk about this over at WMW
