As I said, they load the itch.io server so they can break it, so if a person wants to enter the site they can't do it because they don't get a response, and it's a serious damage for everyone,I'm sure the attacks come from other sites similar to itch.io, they want to cause damage and they succeed, they should simply put an IP limiter,This way they can interrupt the flow before it damages the servers, and I also believe that the attack comes from one of the users registered on the site.
