Building on this question, what happens to users who post 1 or more answers that are flagged as non-answers and/or deleted?
Are they punished or restricted in any way?
If a user posts too many answers that are downvoted and/or deleted, they can be banned from posting further answers.
If a new user posts spammy or abusive answers, or it is otherwise clear that the user is making no effort whatsoever to learn what the site is about and how to use it properly, their account is typically "destroyed," taking all of their content with it.
If a user is posting bare links or other promotional material, but they have made even the slightest effort at contributing useful material or being productive on the site, they are warned instead, and their off-topic posts are deleted.
