Deleted customer placed an order

Hi!
Just completed a screenshare with support. They were unable to advise and suggested I post here in the suggestions tab. We have a customer who has a deleted profile but was able to login and place an order yesterday. Order #58237 Buyer #31504. We are trying to access the customers buyer profile however obviously can't since it was deleted. She was likely deleted back in October of 2020 when we did deleted profiles with invalid emails....anyway can a buyers with deleted profiles place orders?

Never mind I just fixed it and recovered her data. But would like to suggest the in your next upgrade you code in a block that does not allow customers with a deleted profile to place an order.
