I get the warning "Wait! Some of your past questions have not been well-received, and you're in danger of being blocked from asking any more." I am struggling to find any cause for this; I cannot find any question that has been received badly.
I have a total of 8 questions with an average question score of 2.25; only a single question has score 0 and no question has a negative score. The last question was more than three months ago.
I do not have any recently deleted questions.
As far as I can tell I do not have any deleted questions at all. I do actually have two deleted questions from 2012. One was put to sleep by the community user in february 2013 after a year with low views and a score of zero. The other was migrated to stackoverflow and has a score of 2. I have not deleted any questions or answers myself.
I do have two questions that were closed as duplicates, but even so they have a positive score, so at least they were helpful to someone as a signpost. I also am not sure how I could improve duplicates by editing, and I really would like to take care of this warning before I ask more questions.
If I read my reputation history correctly, I have only ever received 2 downvotes, one of which was later undownvoted.
So I really cannot tell what triggered this warning and would appreciate some information here.
What could have caused this warning; is this a bug or is there really something fundamentally wrong with my questions? Is there a minimum average score greater than 2.25 I need to aim for?
I have no intentions of asking more questions if they are not well received; ban or not, that just basic ettiquette. But I am struggling to figure out where I went wrong.
