On the subject of collateral damage: some will point out that tor is a
service with legitimate applications, including some that are close to the
heart of many on this list, such as protection against invasion of privacy
by corporations, defense against persecution by totalitarian governments,
and freedom of association for at-risk women. While these are all valid
uses of tor, I believe the intersection of these uses with posting to the
debian-women mailing list is approximately zero: while we don't want to be
responsible for preventing such people from contributing to Debian in
general, there's no need for them to be able to post to debian-women in the
process, and in many cases it's probably safer for them if they don't do so.
I'm not aware of any legitimate posters to this list that are using tor when
sending mail, and I can't think of any realistic cases in which it would be
necessary for someone to do so.
