There's no such thing as a copyright notice. There's no need for them, copyright exists automatically on any creative work. What you may have been looking for is a copyright license. These give permission to share the work, possibly subject to certain conditions.

The absence of a license simply means you ARE NOT licensed to share the work in any way shape or form.

Your intentions seem to be good but you may want to reconsider.

As we all know, the internet is about the free and open sharing of other people's ideas !

That's a nice sentiment but that isn't how laws work.

Laws are a sentiment but that isn't how reality works.

Indeed. Western legal principle: everything is legal, until you get convicted.

(Technically it's even more specific than that. You don't get to complain or get enforcement just because something is illegal. 3 conditions need to be satisfied. First, it needs to violate the law, as it the law applies to both the complainant and the defendant. Second there needs to be damage to the complainant. Thirdly there needs to be a causal connection between the damage and the law violation. And of course, there's still the implicit condition: there must be a complaint in the first place)

I wish people would keep this in mind when talking about law.
