One days she goes to her kid's school for some crap, another kid that has rubbed one out for her sees her. Or a kid's father recognizes her.
All it takes is one gooner blabbing. If she has a boy, odds are "your mom is a fucking pornstar" is being dropped on him someday in his life. If she has a girl, that's less of a problem. And maybe a positive for gooners in 20 years, I guess.
