That's still the same thing. What matters here is if people expect an actual penalty of any kind. Draconian penalties never help.

On top of that, people are less likely to know whether there is even a law against those things since it's much less intuitively obvious.

What you need to do is make them understand that it's dangerous, not to make them understand that it's illegal. People don't care about penalties unless they expect to be caught and this is one of the things where it's hard to consistently catch people in the act.
