Patreon exists, but I hesitate to contribute to projects/people through Patreon as I want to give them as little money as possible...
We ask our company to set aside of a small amount of money each year, and we distribute it among projects we most used that year on librapay.
There needs to be features like feature/bug-bounties that you can trust even if you don't fully trust the repo-owner/maintainer?
WAT? I pay for porn on patreon and have for years. Maybe it's just live video porn that's banned? I have no idea. AFAIK the artists I'm subscribed to are not hiding their creations. In fact they're all over sites like pornhub, spankbang, etc with their patreon address in their videos. It's all CG or real time 3D but it's most certainly porn.
