Gosh. I don't personally care for AI-made or assisted games, but I don't think anyone should be attacking anyone for making a game with AI as long as it is tagged and credited properly. With a tag, people can opt to filter it in or out, so there's really no reason to stop by just to attack someone willfully. That's just plain harassment - it's abuse, and a reportable offense at that.
Prohibited actions include but are not limited to:
- Uploading viruses or malicious code or acting in any manner to restrict or inhibit any other user from using and enjoying the Service;
- Spamming or sending repeated messages, junk email, contests, surveys or any unsolicited messages;
- Posting unlawful, misleading, malicious, or discriminatory content;
- Bullying, intimidating, harassing, defaming, threatening others, or violating the legal rights (such as rights of privacy and publicity) of others;
I would recommend blocking known harrassers from commenting in your game page. If it persists and multiple accounts are created to continue doing so, you may want to report the abuse directly to the Itch Io team. You can do so via the support page, if I'm not mistaken.
Bear in mind that it is a different thing if you've asked the user directly to try your game and they gave you a bad review, though - and if you've purposely entered Game Jams that prohibit AI works of any kind or level. That's just asking for it - kicking the hornets' nest, if you will.
