I've recently tried recovering an old account I remember next to nothing about without success. Granted, they were very helpful with my attempt, going so far as to ask about any neocash purchases (like, items in the store) that I may have the receipts for or recall, or any neofriends with that account they might be able to contact to verify, but yeah, unless you know the DOB or your email, I 'm afraid to say your chances are likely to be very low :c
