Coming from this meta question, as you can guess, I am actually question banned.
I have read plenty of meta topics about being question banned and the only way out seems to be "Improve your questions"... Fine, I went through all my actual questions, and besides deleting a seemingly useless question that was about to be deleted automatically and a few details on other questions, I don't really think there's a lot for me to do to make my questions better (which is surely wrong since I'm question banned).
I suspect that my deleted questions (1, 2, 3, 4, 5 (undeleted and edited but deleted again by Community user), 6, 7, 8, 9, 10, 11 sorted by most downvotes) are those that weigh the most in my ban and hence are the ones to edit, but as far as I can remember, me deleting these questions was most of the time because, according to comments and/or downvotes, they were not good, and it was simply me acknowledging that they aren't meant to stay on Stack Overflow, even after being edited.
Are those questions going to be a burden forever or is there anything I can do about it? What can I do to make my questions better in order to ask my new question (and not get banned again since I'm not considered a good asker)?
