TL;DR:
The new Terms of Use from Pixiv Fanbox will ban and prohibit all works related to loli, rape, bestiality, guro, etc, basically everything I post here!
This new policy will go in effect on December 15th, that said, I have a month to setup a new supporter place or think on a solution...
So far a discord server for supporters only seems like a good choice for that, but if the user count gets too bigger it will be troublesome to manage...
Gumroad could work too, but sadly it works like a product site, meaning that you might need to pay for every work that is released and I don't like that way.
For now, I want to focus on finishing my current supporter rewards for this month, then prepare myself for the next month.
If you have any suggestion or advice, feel free to share your ideas.
