I declined this flag. This is why:
So-called link-only answers have long been discussed on the network. Nobody really likes them, as they divert people off-site which is frustrating to them, and the links go bad which is doubly frustrating. They should be expanded into proper answers, converted to comments, or deleted altogether.
The post, being a link-only answer, had already been converted to a comment, so no visible information was lost. Undeleting the answer would not have made anything new visible or restored anything to visibility. It also would not have helped the asker, as it was he who posted the non-answer in the first place.
To be clear, the post has some small value, but to be a full answer it really ought to say something more than "set up a scheduled task using winrm".
As for "very low quality" flags on answers, I expect to see these very rarely. There are generally better things to do, for instance:
Wrong answers should simply be downvoted. Don't worry about losing your fake internet points or making the other guy feel bad. (But flag dangerous or malicious answers, such as those that contain an obfuscated
rm -rf /; we will remove those.)
"Answers" which don't even attempt to answer the question given should be flagged as "not an answer". For instance, someone didn't understand the question before answering, posted their answer to the wrong question, etc.
Here's an example of "not an answer".
Spam should be flagged as spam.
And, finally, a "very low quality" answer looks like this. Flag as very low quality when it isn't spam, not an answer or a wrong answer, and deleting the answer is the only thing to do.
