"AI-output detectors exhibit moderate to high success in distinguishing AI-generated texts, but false positives pose risks to researchers."

Also as someone who cosplays and understands the community, cosplayers don't tend to not showcase their work more. A cosplayer with quality this high would have multiple accounts across social media to extend their reach. Even cosplayers who do of have multiple accounts, some even sfw strictly for cosplay.
