When you delete your account
Deleted: your listings that have not sold, saved things, wants, follows, blocks, your bag, settings, notifications, unsent emails, your payout link and your sign-in. Your name, handle, photo and bio are removed. Your ID photo, if there is one, is deleted.
Kept: finished sales and the messages in them, because the other person in each one has a right to their own record and tax law requires sales records. They stay under the name Former member. Anything reported stays with the report.
You cannot delete your account while an order is still going or money from a sale is still on its way to you. Finish or cancel it first and the button works.
