From time to time we all face the issue of users request to delete account and all issues related to this task.
Soft delete
Issue: 2 users in single discussion ask to delete account - all posts are marked as deleted, so it's hard to understand who say what and who resound to who etc
Proposed solution: Soft delete user option which will clear all metadata (avatar, profile description, mail, etc), but username will be changed to something like Deleted#123
and Deleted#7932
where number is ID of deleted user with option to see profile page and see all posts related to this deleted account.
Delete with purge
Option similar to FriendsOfFlarum where all posts created by user will be deleted before user will be deleted as well.
