Account deletion will not delete your messages, which you must do manually or by following this tutorial to ask messages deletion: https://khcrysalis.dev/mass-deletion/ (Take 24 hours or more to fully remove messages). NOTE: Only not-accessible messages will be removed, meaning you need to leave every servers you’re on and close all of your DMs before submitting your demand. If you’re a server owner, you’ll need to either delete the server, or transfer ownership for account deletion to succeed. Account deletion takes 15 days on average (You can restore your account in this time).
