Nor is it the members who might occasionally log out to post about a 'delicate' subject where they would rather keep their anonymity.

I don't know how frequently some members post as troublesome guests, but I trust the opinions of Max, Joe and Jeff when they say it isn't all that often.

On those occasions, I imagine the people concerned might be warned, and if they persist in doing it, they could always be banned. That hardly ever happens, but in theory it could.
