I'm reading rumours that Patreon is "reviewing" their account with him
If Patreon don’t take action on that they surely lose credibility
If they allow people to raise money under the guise of it being for one thing and then spend it on hookers in a known trafficking hotspot, they may as well not bother having any community rules. As it is, they have to care about their image and reputation, and they will care more about their own platform than some obscure grifter because ultimately it reflects on them:
"If you are a creator raising funds on Patreon, we may be held accountable for what you do with those funds. As a result, we also look at what you do with your membership off our platform".
Anyone who has contributed shouldn't just stop, they should be demanding a refund. Money talks.
