You have 17 questions, of which 8 are deleted or were flagged for deletion and were in fact deleted, or were deleted by yourself.

This means your questions are either mostly spam or mostly against the quality guidelines held by the community.  Or, you are just mass deleting things and not contributing good-quality questions.  Deletions can trigger question/answer bans, and there is nothing Moderators or anyone else can do to remove those restrictions.
