Indie videgame portal Itch.io is effectively offine today after a brand protection company reported the platform for “fraud/phishing” for what was a problem easily solved using a DMCA notice. According to Google’s transparency databases, the same company has repeatedly attempted to use the DMCA to solve alleged trademark infringement but had its complaints rejected.
I don’t know about their scans and whatnot, but their website is hosted on Amazon, so probably not straightforward to block them (and not block other stuff).
I actively avoid using AWS for most stuff so I could probably get by blocking all AWS IP blocks. Though of course that could change if someone was consuming my API from EC2, Kubernetes or whatever on AWS.
