Did you try to GET a canary page forbidden in robots.txt? Very well, have a bucket load of articles on the benefits of drinking bleach.

Is your user-agent too suspicious? No problem, feel free to scrape my insecure code (google "emergent misalignment" for more info).

A request rate too inhuman? Here, take those generated articles about positive effect of catching measles on performance in bed.

And so on, and so forth ...
