The limitations period for civil damages has expired. The complainants are anonymous and you don't get paid for making criminal complaints. Making public statements (either individuals or newspapers) which were untrue and cause loss would be defamatory - newspapers aren't going to be writing mega cheques for abuse stories without real substantial proof - not after Leveson and not after McAlpine. Also, newspapers don't pay money for stories if they can help it.
