Data scraping is common these days with so many data driven web applications out there. Regardless of the legality and ethics of the subject, it just sucks to know that there may be people out there who might hammer at your site to “take” all your hard work for their selfish use. That being said, it’s almost impossible to prevent people from taking your data, especially if your data is easily accessible by the public.
You’re probably here because you’re suspicious of possible data scraping activities happening in your website. While there are preventive measures you can take to keep the scrapers out, there are always holes for the smart ones to get through and eventually take the data they want. What we want to do is make it very difficult for the average scraper to hack away the data.
