It's a content aggregate platform that solely relies on people sharing their account tokens. I've been trying to find alternative sites, but i have unfortunately found none. Kemono hasn't updated really anything since the 13th, and seem to be quickly going down the drain.
Kemono party is back up and running, but it's still very slow and it's still not updating accounts from gumroad. The problem with kemono is that its greatest strength is its greatest weakness. Kemono.party has stopped updating fantia and pixiv content, alongside others.
Plus there's still no way to manually add and update accounts from gumroad.
