[tor-project] Ethics Guidelines; crawling .onion

I had hoped to discuss robots.txt instead of Tor2web, but so be it.

I would prefer not to log, and that was the original design. Then when
your servers start pushing 700+ hits/sec, it gets hard to sustain without
some sort of revenue model. And then because onion.link is such a lawsuit
magnet, granting agencies typically don't want to touch it (which I
understand). I considered charging for the service, but if only paid users
could see the content, that would defeat the purpose of the goal of being a
global "whistleblowing platform". So that left the various free models.
Among the free models, ads and logs are the tried-and-true methods. So
it's what I've tried experimenting with. I'm fine being considered the
moral equivalent of a non-profit Twitter which makes a good faith effort to
minimize exposure, yet still tracks user behavior.

That's totally reasonable. I think this is actually part of the reason
tor2web.org is talking about merely hosting code and letting the
implementations brand themselves appropriately.

Well that's a claim. And one that certainly settles the issue. In short,
I am content with the lesser condition of a world where people can opt-out
of tracking. I am ethically satisfied as long that opt-out is easily
available. One concern with this approach is that it puts Tor as ethically
opposed to every large free online service in the world. Including many
that Tor Project uses.

In the worst case I'd think the "privacy all the time" is impractical with
the modern Internet. As for Tor itself I don't think it should keep
identifiable information, but that's different from excommunicating those
who work in organizations that do. This standard would expel many existing
productive members of the Tor community.

Same position as before. I consider guard node traffic to be vastly more
private than tor2web traffic because people using TBB have expressed a
desire to be private. Onion.link is about convenient access. For privacy,
use TBB if you want privacy while using that convenient access---problem

Open to changing that. After the robots.txt discussion.

Fair enough. I've waited since the Berlin meeting last year for this
discussion. And bluntly---it is *really* that hard? Celebrated Tor
products already *directly depend* on the answer being either (B) or (C).
Given several products already depend on it, is rejecting (A) really that

I'd oppose it as well.
