On one side, we have an extremely manipulative individual/group of people.
On the other we have gullible users, some of which are enabling this abuse by donating money and or sharing this content to other people.
Then in the middle of this sandwich we have the platforms, taking their cut.
I've seen other cases like this but on facebook with conjured sob stories that led to justgiving pages.
Not sure what the solution is apart from relying on good samaritans and people looking out for this bad behaviour.
However I can't remember who said it, but someone said "good people don't scale well on the internet"
