What? Have a question similar to Home on the Range of Lists.
Why cannot this user ask the question?
Does that mean that even if the question is posted at Sandbox and well-received that the question will still not be posted at the main site?
The Stack Exchange software imposes a temporary question ban on users who meet a threshold for low-quality questions, determined by the number of questions closed, deleted, and/or having a negative score in a given period of time. You met that threshold, and the system imposed the ban. There's nothing that can be done to remove it, other than just waiting for the ban to expire.
See the help center for more information.
