After all, promoting adult content requires the help of pirate sites like R34 to spread it. The IWARA I'm referring to is a platform where the creators themselves upload their works. Many creators from Europe, the US, and Japan also post their works there. Once they gain a certain level of fame, they might continue posting there depending on their mood. The high exposure increases traffic, which in turn can attract more sponsors. While there will always be those who consume content for free, there will also be those who sponsor because they genuinely like the creator's work.
