It's a strange thing that I noticed on Facebook several years ago, when I was kicked out there because I didn't want to show my ID - reddit seems to handle it the same way, that your sub page remains publicly accessible and users can interact with it, even though you have no influence on it anymore due to your exclusion and no access to the moderation function, of course. Your profile will be banned, but your sub page will remain accessible. On my sub reddit, I had disabled the function for users to comment or post there, because I just wanted to document the content posted there for myself, rather than discuss it in a community. I'm very glad I did that, because otherwise those hateful comments would probably be rampant there now and I wouldn't be able to do anything about it at all. I have asked reddit via the contact form, what will become of my sub, after I myself can no longer influence or moderate it, however, I no longer expect an answer to it and a factual one certainly not.
