In my extensive time on the review queues and 10k tools, there's one thing that's always been bothering me: low-quality answers that consist of no more than a few sentences and often a link to external content without meaningful explanation.
In the past, I've flagged some of these posts in the past with NAA, VLQ, and custom moderator attention flags like "convert to comment". I've had mixed results, ranging from deletion or conversion to comment to the flags getting declined with "flags should only be used to make moderators aware of content that requires their intervention". I've also tried posting comments asking the author to expand on them or to explain linked content, but I can't shake the feeling that I'm not doing enough.
Considering the quality standards we hold ourselves to here at Stack Exchange, I've always felt that such low-quality answers do not merit full answer posts and should be comments. Is this stance appropriate? Ignoring obviously bad posts such as spam or questions posted as answers, how should I handle these answers?
