how come answers and questions are banned without feedback and essential system issues cannot be resolved and re propose again and again (?) Is this question unproperly phrased (?)
I think it's entirely fair that you get some feedback, and that should really be handled at the point that your posts are being moderated. I think sometimes people think that an action is so very obvious that they don't need to say anything about it. I'm sorry people haven't been more forthcoming.
Some of your Answers haven't met the base requirements for answers. Some haven't answered the question (eg, you've just said you've had the same problem), and a couple didn't really make much sense to me, which may be a rushed post, or a language barrier.
Really for a site like this to survive, answers have to answer the question in a clear way. There isn't room in the answer section for chaff. That might seem unfair but it's the cost of doing business here.
I'm not sure why you've only just been answer-banned. Your last flagged answer was a while ago.
You are not banned from asking questions.
There are no specifics in your question so we can only give you general information.
There are several help page topics that go into reasons why questions and answers would be closed or deleted:
Please remember that Ask Ubuntu is community moderated. Sometimes questions or answers are removed that shouldn't have been removed. This is often due to a misunderstanding, so it's really important that you make a good effort to ensure that your question or answer is clear and specific and on-topic.
If you believe that a specific question or answer was removed and shouldn't have been, you should post a question about it here on Meta. Tell us why you think it shouldn't be closed and we can have a discussion about it. Either we will agree with you and reopen it, or we can tell you exactly why it was removed.
Just like on the main site, if you ask a vague question, you can only get a vague answer. But hopefully this gives you enough information to understand why your questions or answers were deleted.
