(30)This Directive should not apply to cases in which persons who, having given their informed consent, have been identified as informants or registered as such in databases managed by authorities appointed at national level, such as customs authorities, and report breaches to enforcement authorities, in return for reward or compensation. Such reports are made pursuant to specific procedures that aim to guarantee the anonymity of such persons in order to protect their physical integrity, and that are distinct from the reporting channels provided for under this Directive.
