Perhaps he should. After all jiff.party closing is what prompted the creation of kemono in the first place
the difference is that yiff died because the guy who was running it wanted to retire. there was no pressure from the paywall sites nor the creators. he just called it a day and retired. people loved yiff so much that they made the k-site.
the circumstances now are different. a lot of the people running kemono quit, leaving 1 admin behind. the paywall sites they are ripping from are now threatening the k-site. nobody wants to volunteer anymore.
if the k-site dies then it is safe to assume there would not be a successor in place. unless a group of people suddenly decided to grow balls and made their own successor or tools.
