What can I do when getting “It does not meet our quality standards”?
There are lots of questions on UML diagrams so why is this question being rejected? A little elaborated error message would not have let me to ask on meta or am i ignorant of rules/procedures
The error is vague intentionally, to avoid users working around it without actually fixing the problem:
I am against being explicit here.... Our check takes into account tags, title and body. We are not going to give breakdown of what was wrong, that is spoon feeding. (source: waffles)
If we provide a "formula" then it's just another way for users to bypass the question quality filters. (source: Jeff)
You provided a perfect example with this post. You used the title "Question is rejected by stackoverflow without exact error", and got the error "please do not use these words in titles: 'Question'". Rather than reword the title, you changed "Question" to "Ques_tion" to get around it. This is exactly the kind of thing people will do if the quality filter spells out the problems with the post, so instead it just says something is wrong and forces you to actually improve the post before you can submit it
First of all, your question's body is exactly the same as the title; that is not good. Second, it is too short; there is not a whole lot of information, which could potentially make the question hard to answer or unanswerable, in which case, it may end up closed. Lastly, it does not contain any punctuation; in my opinion, one should always endeavour to make one's posts clear and proper, and omitting punctuation is a bad way to go about doing that.
It's probably because your subject text is exactly the same as the question you typed in the body.
