A better question is what sort of legislation should apply to every website on the planet, without exception.
Off the top of my head:
- Do not store user information in an unsecure or identifiable mechanism.
- Be transparent as to what parts of the page are ads and which aren't.
- Follow best-practices for accessibility.
- Give @DomeGuy a lollipop if he asks.
Don't ever feel guilty for doing exactly what every last plutocrat and "entrepreneur" would do in your place.
(Do feel outraged that the richest country on earth still demands we work or beg if we don't want to starve to death.)
