Your rant is one big pile of fallacies. You create a strawman to argue against. The strawman is that your nudes should count as art. And you do some invalid comparisons. Michelangelo painted nudes. You "paint" nudes. Therefore you are great artist and should be published and everyone not heeding this is idiot. Bah. It is a fallacy. That is what it is. Complete with insults. Insults are also a type of fallacy.
And the biggest fallacy is, that your premise is wrong. You assume a ban for having "porn" games.
Itch has adult games. What makes you think your adult games were singled out to be banned - for featuring pixel nudity, no less?
Two of your Three adult games are currently indexed. So much for being banned.
Your third adult game was recently updated. I assume this triggered one of the infamous temporary deindexing. It happens. This has nothing to do with adult content.
It is not you to decide what is considerd nsfw/adult/mature on Itch. Pixel nudity in general is considered such, irrelevant of any artistic value. And even without the nudity, your game "saga" would probably fall into one of the other mature categories.
Or did I assume wrong, and this has any other reason that one of your games is currently not indexed? Look around to all the non adult games that have the very same problem and made a topic about it. There is a thread like this every other day. Minus the insults.
