This is extremely important to me and unfortunately in my interactions with the support chat, they seem woefully unaware of the issue. I kept being asked if I was concerned about my site map (?). Disallowing access to my content for GPTBot is a simple flag, as you point out, and yet being unable to edit Robots.txt forces all Squarespace customers to consent to the theft of their work. As a worker in the creative industries, I can't use a service that would so nakedly position itself against my interests. If this is not resolved, I will be moving.
