The problem I see with a lot of these fake phishing schemes is that there is often no consequence for actually failing the test. As you say you just get a generic advice page that the person is likely going to dismiss as a minor annoyance (especially considering they’re already willing to click on it).
I advocate for a radical approach: first time you get advice + a warning, second time you get a stronger warning, third time you get your P45. If you can’t be bothered to follow security guidelines to keep your organisation safe, at least you might be more willing to do so and take things seriously if your actual job is on the line.
