Blog scraping is the process of scanning through a large number of blogs, usually through the use of automated software, searching for and copying content. The software and the individuals who run the software are sometimes referred to as blog scrapers.
Scraping is copying a blog, or blog content, that is not owned by the individual initiating the scraping process. If the material is copyrighted it is considered copyright infringement, unless there is a license relaxing the copyright. The scraped content is often used on spam blogs or splogs.
