Yeah, so a good faith response would be to ask Itch to remove that game and associated copyrighted imagery. Nobody would have really minded that. Uncharitable, I would have thought, but with copyright law being what it is, perhaps legally necessary.

What they did, however, was they told Itch’s DNS that Itch was hosting fraud and phishing, which resulted in their whole service going offline for some hours. That is deceitful and hostile.
