Often after asking a question, the OP realizes that he made a mistake asking the question. Then the question starts getting downvotes and they might be reasonable too. What should I do as an OP to the question? Editing the question is an option; but if the question is really a bad question, we can't improve it by editing unless we ask a totally different question editing the original one. So in that case, if the question itself is outright wrong, what should I do to make it a better question to serve the community?
If it was really an honest mistake e.g. trivial syntax error you missed and saw yourself shortly after posting, you can follow those steps to avoid risk of getting question ban:
- Flag your own question and choose Other.
- Explain you did an honest mistake and ask to disassociate the question from your account.
- Moderator might or might not agree. Be patient and don't flag again.
- If it's not salvageable, delete it.
- If you can make edits sufficient to make it useful and keep within the spirit of the original question, delete it, edit it, then undelete it (to prevent additional downvotes while you are editing).
- Otherwise, if the question is honestly different from the original question, delete that one and start a new question.
Bottom line: delete the question (even if just temporarily), then decide what to do about it. You can see your self-deleted answers, and undelete them at will, so don't worry about deleting it would make it gone forever (nothing ever really leaves the Internet).
If it's a bad question that's not making the internet a better place, then you should delete it.
If too many of your questions are bad, you won't be allowed to ask any more, but no one's perfect all the time. As long as you contribute positively overall you shouldn't worry about removing the occasional dud.
