This is very important in my opinion, similar to #3973 Data protection issues for banned accounts is very important because it prevents malicious actors from leveraging GDPR or CCPA against platforms by allowing the user to access and delete data even when "Banned" while forbidding them from accessing the site.

Obviously just like that one it needs an implementation that allows logging in when banned but not posting, voting, or commenting (likely other restrictions such as well).

Are banned users currently able to delete their accounts?

Edit: they're not, and this issue (letting banned users delete their data) is a distinct bug = #3973

I don't think it's a bug, more of an oversight. It was very much an intentional choice to not let banned users log in. It's just a bad choice because of the severe problems that it causes when it comes to those pesky data regulations.
