random idea, instead of blocking scrapers, maybe detect them (via user-agent, request patterns, ignoring robots.txt) and serve them garbage data wrapped in dad jokes.

  if (isSuspiciousScraper(req)) {
   return res.json({ 
     data: getDadJoke(),
     artist: "Rick Astley", // always
     album: "Never Gonna Give You Up"
   });
  }
