I've noticed reddit doesn't invalidate your cookies even if you click the logout button. There is a button in the site settings under your list of sessions, but I haven't tested that. I noticed it because I delete site cookies often, and paste them in from a file whenever I want to comment. Occasionally click "logout" without thinking. Got creeped out by that year-in-review thing they do once.
