It's broad if they suggest "Marketing".
"Marketing" these days could mean anything. Could mean _anything_ commercial, which includes just having the information on your services, they don't actually have to do anything with it.
If you put ads on a site, you make money from personal information the second someone stumbles on your site, they don't have to register, and "knowingly" means that the user has registered and put an age (Which could also be fake too, but the webmaster doesn't know that). You gather information that could be used for marketing immediately such as IP addresses, browser, any loaded frameworks, engines or plugins, version of OS, screen resolution and many many more.
This is a classic sign of government knowing bugger all about how IT works and what sort of information is gathered in general. As a non-profit webmaster myself, I hope this bill is thrown out (and preferably the people responsible sacked and prohibited from getting another job in government, unless they want to become a janitor).
If "Marketing" in their context means "gathering information for the use of third-party advertisers to allow the serving company to profit from it" then yeah, thats good if they prohibit that, but this is government afterall. Government + IT = A mistake waiting to happen.
Throw the bill. COPPA should also be thrown to the wolves until government makes it illegal for anyone to put a false age, but thats an attack on free speech then, and allowing webmasters to query a database for everyone living at a house and using best guess to see if someone is lying about their age using that IP address at any time is just silly too. That, and they'd just use proxies if they allowed that.
I think there should be a law prohibiting any law which affects IT or Healthcare from passing without professionals and experienced IT consultants in both fields examining them all and giving the nod.
