I had no idea that this was a right-wing movement so I'm not defending them at all, but... even if the "bait" didn't go through "proper" channels, isn't the publicity crippling them socially good enough?

it may be able to be argued that if this person did not present themselves as a willing child to begin with that the perpetrator may have never attempted to pursue such a crime.

But... they could've still chosen to say "no"...
