It's a bug. Logging being off by default isn't a bug though - it's to
ensure that a user turns on logging if they want it and if they didn't
want it, they won't accidentally shoot themselves in the foot.

Two logs that are identical, one produced on purpose and the other on
accident is probably going to present a problem. So the goal isn't to
pretend we can stop jerks from being jerks. The goal of not logging by
default is to prevent pidgin-otr from adding to the problem.

It seems to me that signaling that users are logging would be a nice
addition - if you violate my privacy by logging me, I'd like to know;
that is far from perfect but surely it would create some interesting
social discussions!

All the best,
