I am curious: why is that difficult? Define the fine as a percentage of the revenue of the company, have users report links, and pay someone to check the link and send the fine.

Sounds like easy money... I mean it's very profitable to pay people to check parking lots and fine drivers who don't follow the regulations. This should be even more profitable?
