All regular Stack Exchange sites (including Meta Stack Exchange) have automatic question and answer bans. If a user posts enough poorly received content, they get banned from asking and/or answering.
Things work a little differently on per-site Metas. The FAQ states that one can be post-banned on Meta:
... but the threshold of votes in the auto ban calculation is reduced ...
Then there's this answer which states that
... the quality bans are disabled on all meta sites, ... (with Meta Stack Exchange being the only exception)
All sites, including their meta sites, have an automatic answer ban.
which seems to indicate that all per-site metas have answer bans, but none have question bans.
Finally, there's this recent comment by a Stack Overflow moderator:
... There's no question ban on MSO, but there are question bans on at least some other Meta sites. There are answer bans on MSO.
There appears to be conflicting information here, from various reputable sources (moderators, staff, etc).
So my question is, what's the actual situation currently? Is there a difference between asking and answering (in terms of being banned), and if so, why? Are there different post ban rules on different per-site Metas, and if so, which ones?
This is not a duplicate of the current duplicate targets:
- What can I do when getting "We are no longer accepting questions/answers from this account"? - that FAQ doesn't state anything about differences between per-site metas and Meta Stack Exchange
- Question banning should work differently on Meta - same thing, that only states that the required votes for the bans are reduced, but doesn't state any differences between site metas and Meta.SE
- Is there even an automatic ban on meta? - that simply states that there is a difference, but that text was written back in 2014; this question asks if things have changed since that was written, given the moderator comment above
