They do have an EN section, but a. They've been hit with a censorship wave already (though not quite as bad), and my understanding is it's much worse for the EN section. b. Yeah, not sure if I can even set up there as a foreigner, or how the payout system would work. c. I actually looked up the details on DLsite a while back and their rates are robbery. They take like 30%, even if you're native (for contrast, itch was about 7%, and that's all payment processor fees). Pixiv has their own similar crowdfunding/monthly payment thing, but that's ALSO censored now (although again, not as much as stuff in the US.) But believe me, I've considered, just probably not practical. If Japan unfucked their fees and gave visa the finger as they seem intent on doing, they could make a tidy profit being a haven for this stuff, but it's doubtful that will happen.
