I meant the code for your other scans. We have my original scanner (part
of torflow repo), and one phw wrote, and another set of onion service
attack scanners. TPI might consider also running your scanners in
addition to or instead of some of these. Plus more people running
scanners may mean faster results and easier result confirmation...
Though, this is subject to obvious issues with this being an arms race,
if scans are discovered, of course.

I also agree with your ticket about the time rotation feature. And I'm
not sure we should necessarily publish this info anymore.

I think this and similar ideas should be explored. We're trying to
figure out how to put it all together into an approach that makes sense.
