hypothetically, the best answer for preservation of evidence while still allowing deletion and cleanup would perhaps be the ability to attach info to a ban, in a "select messages/a range of messages to attach to this" or even in the form of moderation info attached to that user? (for that server specifically, of course.)
that way you can retain a record of it in the same way you'd retain, say, a screenshot, but in a cleaner way.

If a moderator deletes all their messages, the image links associated with those messages would also become inaccessible (unless Hampus forgot to delete files belonging to deleted messages?). Servers can keep track of why they ban users, but that does not solve the core issue of having evidence to support that ban, even if you properly logged the why.
