Whenever a PSA comes out through Discord or whatever social media channels about the latest hack or phishing scheme there's inevitably a crowd of people that go "just don't be stupid" because they're getting annoyed by pings. In an ironic twist of fate, some of these people get owned at a later date.
If at least one person becomes more aware from these PSAs then it was worth it. No one is immune to phishing and awareness is the best tool to fight it.
