It's the DoB which is the giveaway (that this is fake). eBay doesn't collect date of birth, but does collect lots of other authentication information.

EDIT: I stand corrected, see the reply by sp332 below.

eBay says the data includes DoB. https://blog.ebay.com/ebay-inc-ask-ebay-users-change-passwor... [edit: better link] Maybe they only collect it for certain customers?

In that case ebay users should probably change their date of birth too ;-).

And physical address and phone number.

Fake your own death and run away to Argentina.
