I'm not a developer, and I already used the "reportaproblem" link which doesn't help. It specifically hides any purchases made before the last 90 days.
I already read How to report App Store rule violations? and that didn't help one bit.
In particular, I want to report an app for an App Store rules violation and it appears that Apple blocked off all standard support routes to save money or something. In this case, the rules violation happened in an update years after purchase (so reportaproblem doesn't apply).
