brags that fan-girling a murderer has led to the biggest audience growth she’s ever had

He's a true crime icon in the making, a brazen murderer (regardless of your stance on it being justified) that is/was super hot. That's the kind of crime that literally soaks women's panties and is a billion dollar industry.

Of course the "safest horny" possible, a politically motivated killer most people (especially women) support, is going to get her growth like no other.
