As I hang out on ServerFault more I'm noticing lots of questions that get only "Yes" or "No". I think this is a worthless, rep-grab answer. They are especially worthless when they were able to post "No" first, get voted to the top, and bury the nice paragraph answer on why its "No" that's posted hours later.
While I agree that sometimes a simple "Yes" or "No" does completely answer the question, 90% of the time it simply answers a question with more questions.
Even once it was because the answerer thought the question was low effort, therefore deserved a worthless answer. I disagreed with the question being worthless, but it also makes his answer worthless for anyone else that tries to go to the question for more information. For reference someone else posted a very detailed answer which shows that yes, this question is really more than a yes or no question
The issue though is that several times the people doing it have over 10k rep, which makes me hesitant to flag. I also don't want to burn through my flags and clog the flag queue if mods are just going to ignore it.
Should I flag answers consisting only of "No" or "Yes"?
