Yeah, go back to page 2 of this thread & check your snapshots connection lists and my response in posts #14 and #19 about who they are. They are hostile BOTs.
The Hostiles file has the entire 66.212.0.0/16 blocked.
Re: Hostiles file: I admit the original BearShare hostiles file was somewhat over-heavy but it was easier to adopt that list than start from scratch. I added blocks from my personal prior & later experience, and from File_Girl's Gnucleus blacklist and from GTK & Phex. File_Girl's list included media & software companies, police and investigatory groups from worldwide.
A big part of the problem with the original BearShare hostiles is that a % of it is out of date. Also, Aaron Walkhouse had a habit of adding hosts whom were accidentally sharing spam. He never removed hosts after adding it seems.
