So last year I got banned from asking questions on SO. This happened when I was cleaning up after my "bad" questions. This was a time I actively started using SO and from time to time I would ask questions which weren't necessarily helpful to others. So I decided to delete those questions. Unknown to me were the consequences. After deleting several questions I received question ban.
I can understand the reason behind it, but I'm not quite sure why this ban is permanent. I improved my questions and undeleted them. I also started giving back by answering other questions. Yet I'm still not able to ask anything on SO.
Why is there such an aggressive ban in place? Wouldn't at least a single warning be better? I had no idea such a ban would result from my actions.
Either way, it has been over a year now and I'm wondering what my options are to resurrect my question privileges? From what I've read I have to improve my questions. But you can't polish a turd (unless I'm a mythbuster) and I already did my best on doing so.
