Yeah, and Hilton continued behaving shady afterwards, like a con man.
One difference between Hilton and Flynn is that Hilton was involved in owning companies with stakeholders (both staff and fans) caring for it. Someone with a checkered past going back to a career which could allow him to continue should have raised alarm bells. Flynn’s history of dangerous driving would raise alarm bells if he was going for a job as a lorry driver, taxi driver or courier. As he is going for a job as footballer, I suspect we can sleep easier because he doesn’t need to drive professionally for it, unless we’re planning on him playing on the wing in a flash Range Rover.
Also, you speak of fraud as if it is some minor crime. It isn’t. It’s a crime that ruins people.
