A month ago searching for "Olympus" on C.AI showed character results about Heroes of Olympus, a spinoff of Camp Half-Blood series of novels. Today I searched for the same thing and noticed that these characters have disappeared. Only generic "Mount Olympus" results appear now. Is this because C.AI is now enforcing it's policies and removing characters that infringe intellectual property? AFAIK they never allowed IP infringement in the first place, but they didn't enforce their policies previously.
(Tagging as "chat" as I couldn't find a tag for Character.AI)
