No. Not confirmed at all. The site went down around the election iirc and before that the importer wasn't working. Before the site went down, the importer got fixed, so things could be uploaded again. And then it went down. It stayed down for a while, mostly cloudflare fuckery, and when it came back up it had the default bootstrap landing page. That's been up for most of the time yiff party's been up, but there's also been one MySQL error, and one instance where there was no webpage whatsoever (no source code either, just blank white) which was for the entire domain (e.g. y.p/creators, y.p/hunterbidens9point5inchschlong, etc.)
Don't know what it's current manifestation is, but you don't get those differences in the website if it's been abandoned...
data.yiff.party or whatever it is is still up, so my bet is that the site is getting revamped with its current data and getting set for re-release. I'm guessing that the admin is setting up the architecture for automatic image compression (save on storage space) and spam file recognition.
