I'll let our admins know, but do you mean the adult game that takes payments? Because those aren't allowed on itch.io right now, as has been amply discussed in the community for months. And your other ones appear to have potentially objectionable content, from what I can see.
I have 3 projects up. Project Sweepurr is set to allow payments and I know it is deindexed since the drama. That one is not the project in question. I know that paid nsfw games are not allowed on itch.io because of payment processor tyranny with their censorship.
The projects in question are the other 2 projects (Sweepurr demo and Furrmatch) which are set to "no payment". Sweepurr demo is a demo version of the project Sweepurr. I have seen other devs having a "demo page" of their paid games so I tried to do the same and it got indexed and than deindexed a day later.
As for my latest project Furrmatch, it has been set to no payments a long time ago and was properly indexed for a long time, than it got deindexed for no reason and has been since (22ish days ago). (edit: clarity of the situation better explained)
