A horde of pirates is undermining Patreon’s financial structure, reposting paywalled pornographic images on an illicit website for free. The makers of these images are furious that internet denizens are putting their livelihoods in jeopardy to score free porn.

Crowdfunding website Patreon was known as a haven for uncensored erotic games that couldn’t exist on traditional storefronts, but a recent crackdown on adult material has users worried about the future of such fringe games.

Breeding Season, a sex game that billed itself as “Harvest Moon meets Hentai,” was one of the biggest projects funded on Patreon: according to tracking website Pledge Society, the title was raking in a whopping $42.3k a month. But as of yesterday, development on Breeding Season has ceased completely.

It’s not easy to make money running a video game website. In June 2015, popular mobile outlet TouchArcade said it was having cash problems and asked for help, and lots of people did—including mobile developers. But recently, following a mixed game review, one developer decided to pull their funding.
