The only phishing e-mails I receive are from my employer. As a matter of process I report these e-mails like a diligent lackey, then upon receiving an e-mail congratulating me on passing their test, I report that one too. I think the non-test phishing reports undergo manual review so I hope I'm wasting someone's time somewhere in payback.
Still haven't forgiven them for a tone-deaf 'we care about you during COVID' phishing e-mail they sent when everyone was genuinely struggling.
