I had that thought as well, maybe they are taking direct payments and that's the work around. I would do direct payments if I knew for sure it would fix my problem. I have NSFW turned on, so after my game was deindexed, I browsed around and was surprised how many "popular" games were for sale, so maybe they are taking direct, who knows.
When my game was indexed, it was showing at the top on a couple of my tags and even on the top sellers page. A good amount of my traffic was coming from Itch discovery. None of my tags work anymore, only way to reach it is by direct link.
Leafo told me to try unmarking the game as sensitive content, however it was originally marked by a mod which is what unindexed me, so I don't have the option to change it anymore.
I did get my old Demo page indexed again last night by marking it as sensitive and uploading my demo with payment option turned off, so that's at least a small win.
