@Yakotarun @Ota1504 @JapanAnon If really good alternatives existed, yes. For example, on pixiv I can post a completely naked loli who only covers herself with her hands, and rate it as "all-ages/general", with only the "includes adult-content" flag set, because according to their rules it's only implied nudity and doesn't even need an R-18 rating. For R-18 pics/animations the required mosaics are annoying, but besides that it's difficult to find another gallery site with such relaxed rules. Iwara sounds good in theory, since it allows anything fictional, and doesn't require censorship, but discoverability sucks so much on that site these days, since you basically rely on people to browse the "recent videos/pictures" page, and your thumbnail being clickbaity enough to stand out from the masses of chinese spam. Once your video/pic drops off page 2 or 3, that's it. So if you post your well-made hard work with shitty timing, it will get easily flushed off the visible pages by a load of shitty low-effort content.

I guess hosting my own site would be an idea, but I would need to find a hoster that doesn't cause problems, and find an anonymous domain registrar that doesn't steal my domain. But that would move the problem from getting seen on a crowded site, to getting visitors to even visit the site. The idea behind onionket is pretty nice, but an artist would need to provide something really good, so that people are willing to use tor to access his stuff.
What's that Mitra he talked about btw? Some kind of crypto shop system?
