into scores that he found to be too low. Doyle defended the grading system, believing that every scale should be converted directly to that of the website, with its lowest possible score being 0 and the highest 100. Further criticism was directed to the website's refusal to publicize how it aggregates scores. According to Doyle, publishers often try to persuade him to exclude reviews they feel are unfair, but he said that once a publication is included, he refuses to omit any of its reviews. A Washington Post review of Uncharted 4 was assigned with a rating of 40/100 by Metacritic; this was the only negative review of the game. Readers who disapproved of the review petitioned Metacritic to remove the Post as a trusted source. As a result of its perceived negative influence on the industry, several reviewing sites, including Kotaku and Eurogamer, have dropped numerical reviews that would appear in Metacritic, instead favoring a qualitative assessment of a game. Kotaku also highlighted a practice alleged to be used by some publishers who use Metacritic scores as a way to leverage more favorable terms for the publisher or deny developers bonuses should they not reach a certain score. Doyle countered this by saying "Metacritic has absolutely nothing to do with how the industry uses our numbers... Metacritic has always been about educating the gamer. We're using product reviews as a tool to help them make the most of their time and money." Metacritic has also been criticized for how it handles banning users and their reviews, with no notice or formal process for appeal. Critics and developers have pointed out that a product can suffer from rating manipulation by users, as by garnering low ratings that purposely damage its reputation or by receiving high ratings from throwaway accounts to make it appear more popular than it actually is. Signal Studios president and creative director Douglas Albright described the website as having no standards. In July 2020, Metacritic added a 36-hour waiting period for user reviews to be posted for video games at launch in an effort to reduce user score review-bombing during that period by users that have not played or barely played the game during a period when most players have not finished the game. Some have noted that Metacritic scores for modern video games may not be accurately reflective of a game's state in the future due
