About this plugin
This plugin will help keep away programmatic content scrapers by protecting your VALUABLE CONTENT with a three layers of checks.
Similar to Google: Show CAPTCHA for suspicious “visitors” and never lose the REAL ONES.
Layer 1: This is the most basic stripping out programming languages user agents like cURL* (used by PHP and many others), libwww-perl (used by Perl language to scrape websites), scrappy (library used by Python, Ruby) and many others.
Layer 2: A bot will always browse very fast and it will be able to “browse” a lot of your pages within a very low seconds range. The plugin detects this and shows a captcha to the “visitor” to make sure it isn’t a bot.
Layer 3: Complex behaviour computation – a bot is set to crawl your site at the same time using a cronjob. We detect that by using a three day comparison. If such a scraper is detected, the guest is asked for a CAPTCHA to ensure it is legit!
Also, to keep you updated with what’s happening in the background, WP STOP CONTENT Copier is logging everything so you can analyze: IP addresses asked for CAPTCHA and the result: (COMPLETED CAPTCHA OR FAILED)
