bans accounts they think are AI assisted?
Again, if this were true, we would expect to see a consistent pattern—but that is not the case; every day, more and more AI-created games appear on Itch.
What Itch has done is implement a tag and an exclusion system: if I, as a user, do not wish to see AI-created games, there is a quick option on the left-hand side to filter them out of my search results. Therefore, it would make no sense for the staff to randomly ban a few creators simply for using AI.
In your specific situation—and noting that you mentioned in your initial post that you did not intend to discuss any particular ban—it is possible that your account has been flagged as suspicious for some reason. Perhaps you violated a rule, used bots, or did something else that caused the system to flag your entire account—rather than just an individual game—as suspicious, which is why none of your games are appearing in the index.
If this is the case, you should contact the staff to discuss the matter with them.
