According to the documentation:
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 be blocked from using the site.
- 9 questions
- 1 deleted
- 3 zero votes of which 1 put on hold as unclear what you're asking
Once the "on hold" status was removed from this question, the warning disappeared when I clicked the Ask question button.
Why does a danger of being blocked from asking any more message appear while there is not a significant number of heavily down-voted, zero-voted, or deleted posts?
