You can't speak for that other person. Let them respond for themselves.
Sounds like you're more interested in competing with someone than talking about ideas.
Would you really care about any positive stories after seeing what you saw?
...yes? Of course? I don't automatically dehumanize that hypothetical person for their deeds, whether I approve or not, or believe there should be consequences. Like, doesn't Facebook collaborate with law enforcement in tracking down predators and scammers and the like? It's not as simple as "bad. go away."
You should remember enough to make a proper argument, dude. A solid conclusion needs solid support.
