Amazon has gotten contact addresses for me from Gravatar being hacked, so it's not just a matter of "you should have known linkedin will share with anyone". My cat gets spam to his facebook-catname@example.com address. I created the address to segregate his mail from mine. It was only used to sign up for his Facebook account. The cat is long dead, but he still gets spam from whomever Facebook sold/leaked/trusted partered his information to.
