Skateboarding is probably one of the worst subcultures when it comes to older guys hooking up with underage girls. It was always around and it will change but first people need to admit it's a problem. The biggest obstacle is the guys who don't want it to change. They'd rather live in and celebrate that filth. If you never saw that in your local scene, especially in the late 90s and early 00s, you're either lucky or just blind to it. And if the guy is in his twenties and the girls is a teenager there is no consent, period. They avoid older women because they know they'll get called on their bullshit so they target younger vulnerable girls still trying to figure out who they are.
