This question already has an answer here:
However I would like to address a specific case: feature requests. I recently did one that was not well received. Feature requests questions might be downvoted when one disagrees that the feature should be implemented. Now, if you get a ban, the guide says:
All questions are expected to be useful to future visitors, too, so put effort into writing with proper grammar and spelling, formatting your post so it can be read easily, and providing as much detail as possible about your problem and what you have already tried. Reading your question out loud to yourself can help you understand what it sounds like to others.
However, the automatic algorithm does not know about the quality of a post, it knows about votes, and for feature requests the votes can be very low even if the quality is ok. That puts in danger low rating users (but maybe experienced from other Stack websites) who want to propose an idea, and contribute to the website.
Is this is a relevant problem? How could be this situation prevented/mitigated?
Note: I know one "bad" question alone is not sufficient to get the warning. But since I got another question closed, I got a warning and for example now I am at risk even by posting this very question. Where I think I did my homework, but God knows who I can find out there in this dark night... :)
(This was the status of this question when justcool393 updated his answer)
Now I read about Get rid of the question ban on Meta; suspend actively harmful users manually However, why is the warning still so scarying?
Stack Exchange has automatic filters in place to ban questions from accounts that have contributed many low-quality questions in the past
(Note: I am still readying details, but I urged to edit here to save this question from being closed)
(Then the question got closed so I moved to a new, more specific question)
