4. League Of Legends (PC)
League of Legends is one the most played games in the world. And with 32 million registered users, it's near impossible to moderate a community so large. If you have played League of Legends, you might wonder why it is not higher on the list as it has been voted as the worst online community for the last 2 years and is constantly being bashed in forums and message boards. The reason is simple-the game is constantly developing. Developer Riot released a peer review system in May 2011 and from there the game has considerably improved. But it's still one of the most vulgar communities with abuse and harassment generally going unchecked. The implemented system to report players can be easily manipulated which results in legit players being reported by the losing team. LoL will always suffer from boosters and cheaters who intentionally abuse the system. It is improving though and with a few key additions, Riot could transform its community.
