If the bots are making the queries directly and the data can be
extracted with timestamps and a reasonably low false positive rate, Team
Cymru would be more than happy to take the data and report it out to our
hundreds of subscribed and vetted ISPs/ASN/netblock owners, with or
without attribution to the contributing party/parties as desired by
them. Anyone who is looking for a clearinghouse for this data can feel
free to ping me offline (or respond on-thread here if you so desire) to
