People post a bad question, for any of the following reasons:
- Not researched
- Off topic
- Poorly written/formatted
- No sign of any attempt to solve problem
- Classic help vampire question
This gets downvoted and often without comments.
It's exhausting and tiring work to constantly coach newbies about how to improve their question, because most don't bother to update and oftentimes the only response you get back is "f you why u so mean" types of feedback.
Whenever a question from a user with less than 50 reputation receives a downvote, automatically generate a comment from the Community user which says:
Welcome to Stack Exchange! You might have noticed your question received a downvote. Voting here is anonymous, but you can find possible reasons for this here as well as suggestions for how to improve your post. You may also find it helpful to read the [FAQ] to better understand what types of questions are on/off topic.
Note the link to "here" can link there or to a more comprehensive "what does it mean when I got downvoted?" post. The [FAQ] link would be to the site on/off topic section.
Reason this resolves problem
If I downvote a question, I want to help users learn but I am not going to try to search for the diamond in the ruff constantly.
I don't think I'm alone in this.
Adding customized comments is a lot of work. There are a ton of crap questions posted on SE. Honestly, I don't care that I'm "supposed" to be willing to post personalized, "how to improve your post" comments. It's a pain to constantly put these on questions when the majority of the time they get ignored anyways.
Another problem is that if you do post a comment trying to help, you often get attacked by the asker and blamed for all the other downvotes. This is frustrating and not a positive reinforcement.
But I will upvote a comment that gets autogenerated as a "support" type of thing, because it is very easy and painless.
And, honestly, if someone gets a comment like that explaining how to improve their post and doesn't bother to update their post or request clarification I really, really, really don't care about their feelings being hurt.
