I recently had a couple of questions from the same author where I had provided answers but the author did not respond and the question was flagged as abandoned. I did a Request Attention on a profile because none of their questions had ever been closed. All were abandoned or forced accept.
The advice I received was that there is no need to address the issue with the author directly since they will receive notices, abandoned questions are handled automatically, and eventually Experts will stop responding to serial abandoners.
So my question for discussion: Is this true? Do you as an expert look at the author before you provide an answer? Second, are there enough new experts gunning for points that a few people ignoring posts would have any effect?
