/*
    Note: This may not be 100% GDPR compliant as it is still being worked on.
    Logic:
    If arg is update, respond with message about updating their user profile in Discord as there is no information stored in DB
        that is user updatable
    If arg is download, DM the user a copy of the raw data from the database (unsure about format)
    If arg is delete, confirm with user - if yes deregister and then delete from db
    If arg is ignore, confirm with user - if yes confirm if they wish to delete existing data - if yes run delete method, if no
        add user to ignore list
