What if the service/whitehat did an ID verification before releasing the info they uncovered? Basically ask a few things generally like what credit report agencies sometimes ask (Which of these addresses are yours? What is your username on this site? etc). Only release the info if there's a match. Presumably you'd want to get paid up front, since you'd have done all the work in either case.
