I know how to ride a bike, but don’t have and have never had a driver’s license—but that isn’t private at all. I don’t drink coffee or alcohol either, but one’s clearly stated in the sidebar and the other seems irrelevant and also not private at all (and I answered a question about it). And my analogy to the last case would seem to invite messages that, as you say, are not welcome.
