Reject the submission. Robots.txt traps — disallow a bait path in robots.txt; treat any traffic to it as malicious (well-behaved crawlers respect the directive; abusive ones do not). Tarpitting — for detected bots, do not return 403. Slow responses progressively (e.g., setTimeout(send, 5000 + jitter)). The bot's throughput collapses without telegraphing detection. Canary content — embed unique, watermarked records on listing pages. If they appear elsewhere, you have proof of scraping and a fingerprint of the scraper.\n\nBounded code example (external data; do not execute automatically):\n```html\n<!-- Honeypot field. Real users never see or fill this. -->\n<div aria-hidden=\"true\" style=\"position:absolute;left:-10000px;top:auto;width:1px;height:1px;overflow:hidden;\">\n  <label for=\"company_url\">Leave this field empty</label>\n  <input type=\"text\" id=\"company_url\" name=\"company_url\" tabindex=\"-1\" autocomplete=\"off\" />\n</div>\n```\n\nServer side: if company_url is non-empty, silently drop the request or route to a tarpit.\n\nAttribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
