Edit: added more precise info at the bottom.
It was brought to my attention today in chat discussion with moderators of other SE sites that we don't seem to have all of the question-limits that SO has, after I mentioned a particular user that was posting (and often deleting after downvotes) a large number of very low quality questions.
It looks like (on the basis of that discussion) the Community team (i.e. people who do the admin work of SE) is looking at the impact of doing so (how many users would be affected), but I figured I would raise the question of whether people would seek this if we had the option.
We already have some limits in place, because I saw a user hit one the other day. I don't know what is in place and what isn't right now, but it looks like we may not have all the limits our own help suggests we do.
Having all of it in place would reduce the ability of new users to post many poor questions - they would progressively only be able to ask weekly, then only after improving their existing questions (though it's possible a few of our current users with very large numbers of downvoted and deleted questions and very few upvoted questions might not be able to lift the block at all).
If you think it's a bad idea, feel free to downvote (it's okay, that's how this is supposed to work) and/or comment or post some specific thoughts. If you think we should seek to do it, you know, do the converse things.
If there's some support I could turn it into a feature request.
Edit: more precise information
We currently have the rolling rate limits but do not currently have the full-bans where you can't post until you fix some old questions (including fixing self-deleted ones and undeleting).
