Since it is very easy to steal content from the web by simply copying and pasting, the problem of online plagiarism is growing.[citation needed] This phenomenon, also known as content scraping, is affecting both established sites [3] and blogs [4].
Free online tools are becoming available to help identify plagiarism [5], and there is a range of approaches that attempt to limit online copying, such as disabling right clicking and placing warning banners regarding copyrights on web pages. Instances of plagiarism that involve copyright violation may be addressed by the rightful content owners sending a DMCA removal notice to the offending site-owner, or to the ISP that is hosting the offending site.
It is important to reiterate that plagiarism is not the mere copying of text, but the presentation of another's ideas as one's own, regardless of the specific words or constructs used to express that idea. In contrast, many so-called plagiarism detection services can only detect blatant word-for-word copies of text.
