I saw this in the logs for one of my sites for 3 or 4 months straight (seemed to let up last month). I have tried looking at the pages listed in my logs as refering pages and cannot find the links to my site/pages.

My SE standings have been rather sporadic since then. The affected site took a dip in SE standings at first, but it recovered and is still ranking overall ok, but there has been an across the board PR drop of 1-2 depending on the page.

Any ideas?
