Temporary deactivation
Use deactivation when you want to hide your presence for a while without losing the account completely.
A deactivated account can usually be restored by signing back in, as long as it has not moved into a permanent deletion flow.
Permanent deletion
Permanent deletion should only be requested when you are sure you no longer want the account. Make sure active orders and disputes are resolved first.
Deletion is not the same as logging out. Once permanent deletion completes, the account cannot simply be reopened later.
