I gave you the general rationale for why downvotes are anonymous in my answer to your other question. I should also point out that neither moderators nor anyone else can review downvotes since we do not know who cast them. Mods have no access to this information, no more than you do. As for the specific answer you mention here, you were answering a question about this error message:
mount: /backups: special device /dev/sda1 does not exist.
Your answer was:
You might check under
/dev if there is still an
sda1 entry. If not
you can create one.
ls -l sda*
I'm afraid the downvotes you received were perfectly reasonable. First of all, the SE sites are not forums. This is a bit of an obsession around these parts: we are not a forum, we are a Q&A site. This means that every post must be either a question or an answer. Suggestions for troubleshooting aren't providing an answer. The right place to post those is as a comment to the question.
Now, I completely understand that that might feel like a catch-22 situation for a new user since we also have a minimum reputation requirement for posting comments, and you can't post a comment if you have less than 50 rep. This is to avoid spam comments (and yes, those would be a big problem, we get a lot of spam).
Getting 50 rep, however, is just a matter of getting 5 upvotes on a question or answer. It's a pretty low bar and one you can reach very quickly if you just participate on the site for a bit. So, until you have that, please only post answers on questions where you can provide a full, working solution. Once you have 50 rep, then you can leave comments with troubleshooting tips that can give you the information you need to post a complete answer.
So, leaving a comment asking whether
/dev/sda1 exists might have been understandable, but then we already know it doesn't exist. That's what the error message is telling us. The problem would never be about whether
/dev/sda1 exists on the filesystem, the question provides us with a wealth of information that clearly shows there is an issue with the disk. So really looking at
/dev/sda1 on the filesystem is just completely irrelevant.
That said, there are a few stylistic issues too since you don't need to
/dev to see if there is a
/dev/sda1 file, you can just do
ls /dev/sda1 and running
ls sda* will show you all filenames starting with
sda, not the specific one we're looking for. But OK, those are minor.
In summary, your answer ignored most of the information provided in the question and gave a mostly irrelevant command that wouldn't help anyone who is trying to solve this problem. So the downvotes here are exactly what you ask for: they are being used to "prevent truly going in the wrong direction".
You mention rudeness, but I don't see any evidence of that whatsoever. These are the comments under your answer:
None of those are remotely rude. On the contrary, I see two users who took the time to point out issues with your answer, exactly what you are asking for! As for people not responding, that's because they never knew you answered. You need to ping the user with
@username in order for them to be notified. Your comments did not, so the people you were answering had no idea you had answered them.
More importantly, you completely ignored the points the comments raised. You didn't include an example or flesh out your answer and you didn't address the complete absence of any command or even rationale one could use to create
/dev/sda1, which is what your answer is suggesting.
In conclusion, you really shouldn't take downvotes personally. They're not about you, they're about your answer. Our objective here is to build a library of useful questions and answers that can still be useful years from now when someone else has the same problem. Everything that happens on SE sites should be seen through that lens. It is not about the users, it's about the content.
