Since January 29th, this new member of our community has posted six questions. None were models of clarity, but some received good answers which exhibited quite a bit effort on the part of the answerers. The member in question has not accepted nor even acknowledged any of answers given.
I think it would be good to discourage such behavior, but I can't think of anything I can do except put this person on my do-not-answer list and to ignore them in the future.
Does the community have a policy for handling this kind of problematic behavior? Or am I wrong in thinking this is a problem?
