Absolutely. The people who get caught doing this stuff generally haven’t done much to conceal their identity and get caught with evidence of other unreported offences on their computers. It’s horrifying to think about what the sophisticated ones might be getting away with.

I overlooked the word ‘half’ in your original comment and brought up the dick pics because they make the crime so easy to prove. I’d say all of the conversations were illegal grooming, but it’s harder to prove that the person had the necessary intent when the conversation isn’t explicitly sexual.
