tomashastings, did you ever figure out what's causing these for you?
On my end, I can't seem to isolate the happenings.
ISPs from random hits: Comcast, prominent Indonesia ISP and a Portugese ISP. (These don't appear to be from servers, but users.)
I'm wondering if these are potentially zombified computers running a poorly-coded bot of sorts?
