My traffic has been very slowly inching up again.
RoadRunner, Comcast and Verizon are the top ISPs.
I don't really have a way to track which IP numbers match up to which ISP in order to send them a list, though.
On the up side, I wrote a blog post about it and now I rank on the first page in Google for "zombie robots." (!)
Oh, I also tried Cloudflare for a bit, but it only identified around 300 or so possible botnet hits out of thousands and thousands. Those were probly the ones I *normally* get.
