Is this the analogy you were going for?
If someone told UPS a package has drugs in it, they'd say, "that's nice, talk to the sender" and then deliver the package. If someone tells Cloudflare, "that content is illegal", they say, "that's nice, talk to the site owner".
Would they? Or would they turn the package over to the police?
Isn't more simple and correct that you contact police directly, present the evidence, have the authorized person to decide if the thing you claim is illegal or that the evidence is convincing then intercept the package.
Like in the case with a website, some dude complains that some other dude stole some css, now you need a detective to find the real author, licenses and then detect if is fair us ... this seems to be a job for police/justice. It is not a clear case like you are hosting an entire Disney movie.
