It is indeed strange that after making the user "anonymous," all their old posts are under the same name. So we know the same person wrote multiple posts.

1. Use Google search
"But he has asked for the account to be annonymized."
Making the site searchable for "user:3624" doesn't conflict with that. His name will still not be shown. Making a dummy account with the name "user3624", like Federico Russo suggests, will allow you to access a list of "user3624"'s answers, whoever that is. It would be just as anonymous as it shows now ...
