The implication is that if you want to find shady shit, you go looking for it with those who give off an air that they have something shady.

Usually, someone who’s done or said things that have stirred up controversy or general media attention in the past.

The ones that go unnoticed are the people journalists have to spend a paragraph explaining who this person is and why they’re a big deal.

Much easier to get a scandal published if the public already recognise them and think “yeah, I thought there was something off about that person”.

Edit: typo.
