Stack Exchange has automatic filters in place to ban questions from accounts that have contributed many low-quality questions in the past. These filters help keep the quality of our sites high. The exact formula for the bans is not disclosed, but users are only banned if they have a significant number of heavily down-voted, zero-voted, or deleted posts. One or two bad posts will not cause you to to be blocked from using the site.
Users who are banned from asking questions see the following error message when trying to post a new question:
We are no longer accepting questions from this account. See the Help Center to learn more.
Question bans do not affect other privileges, such as commenting or voting, and there is no indication to the rest of the community that a particular user has been banned.
How can I get out of a question ban?
The ban will be lifted automatically by the system when it determines that your positive contributions outweigh those questions which were poorly received.
Stack Exchange cannot lift question bans by request.
The only way to end a posting block is to positively contribute to the site; automatic bans never expire or "time out". Begin by fixing your existing posts; do not just post the same question again. All questions are expected to be useful to future visitors, too, so put effort into writing with proper grammar and spelling, formatting your post so it can be read easily, and providing as much detail as possible about your problem and what you have already tried. Reading your question out loud to yourself can help you understand what it sounds like to others. Here are some additional tips for writing good, useful questions:
