Before I was getting around 1k a day from Google which I was fairly happy with considering I don't have much text on my site and it's basically image based, but since the last pr update it has gone right down, so far this month I am only getting like 150 a day! In July I got 30k in the month and last month it went down to 20k and so far this month it looks it will will go right down.
I am still indexed, and I'd find that hard to believe anyway. And I cant give the url out as its adult site, just wondered if it happened to anyone else before maybe.
Well I don't think anybody could help you why you've got sudden drop in SERPS if you got it. Beware of linking to bad neighbourhoods! Check your out links is the only one which came to my mind.
