That's assuming that everyone has a good grasp on what's going on, and considers this funny-picture-App to be their top priority.

We HN users might be aware of this particular issue, but there's thousands of products that we use, because we're unaware or don't have the energy to fight.

So with all the exploitation, abuse and pollution that you indirectly support, why do you expect most users to draw the line at a weird website?

Not simple at all.
