[tor-dev] ResearchEthics

[Rishab Nithyanand]

Forgive the lack of inlining.

I've been meaning to respond to this for a while. For what it's worth, I
completely disagree that outright "banning" of certain data collection is
the right answer here. There should be a standard "let's weigh the risks
vs. the benefits and make a decision" for any/all cases. In most cases,
there are ways to perform data collection over Tor (even trying to
understand the makeup of hidden services) in a way that does not compromise
privacy/security -- e.g., the harvest reports only the "class of the .onion
site" and not the actual site itself. This answers the question the
researcher is interested in, without compromising or revealing the .onion
directly.
