This "Internet language" of incorrect spelling and improper grammar also contributes to Yahoo! Answers' reputation of being a source of entertainment rather than a fact-based question and answer platform, and for the reliability, validity, and relevance of its answers. A 2008 study found that Yahoo! Answers is "not optimal" for questions requiring factual answers and that the quality decreases as the number of users increases. One journalist observed that the structure of Yahoo! Answers, particularly the persistence of inaccuracies, the inability to correct those inaccuracies, and a point structure that rewards participation more than accuracy, all indicate that the site is oriented towards encouraging use of the site and not towards offering accurate answers to questions. The number of poorly formed questions and inaccurate answers has made the site a target of ridicule. Likewise, posts on many Internet forums and Yahoo! Answers itself indicate that Yahoo! Answers attracts a large number of trolls.
