Did you do this test recently, since mid August 2013?

While I'm sure that some spammers send email via Tor, I don't see why
botnet owners would do that. I doubt that they care much if some of
their slaves get blacklisted.

I may have to disagree with myself. I just looked at
<https://metrics.torproject.org/performance.html#connbidirect> and the
fraction that mostly writes has increased dramatically since mid August.

And so I propose a more-specific hypothesis: this is a botnet for
collecting information from slaves, not for sending spam. If so, I
wonder what it's after.
