Media Molecule is removing user-created levels for LittleBigPlanet where they feature copyrighted material or other unsuitable content.
While one of the biggest draws for the PlayStation 3 game is the ability for users to create their own content, such freedom is providing a headache for the developer faced with moderating submissions for download.
Simply removing the offending content has sparked some complaints from the fan community, but Media Molecule has said that it is working on a solution to better communicate with users as to why levels have been deleted.
"We're reviewing the moderating system currently to provide better feedback on why levels are moderated," said a spokesperson for publisher Sony on the official forums.
"Primarily, any level that is reported using the grief tool will be checked over by a moderator, at which point they'll examine it in line with the EULA (End User Licence Agreement). If a level is found to be in violation of the EULA it will be moderated and you'll receive a message to that effect," explains the post.
"We're moving towards a system where additional information is given, however for the time being if you don't want your level moderating avoid anything unsuitable for users of all ages and copyright content."
Levels featuring content from games and other media including Metal Gear Solid, The Legend of Zelda, Batman and Scrubs have all been removed from the servers – with users complaining that they have spent hours creating content and have no back-up of their work.
Sony has said it hopes to inform users how they can tweak their creations to make them suitable, rather than be forced to delete the entire level.
"We want to ensure that creators' levels are only permanently removed if they warrant it. In most innocent cases a simple tweak to the level may be required and that's what we're working on communicating," said Sony.
LittleBigPlanet was released last Wednesday in the UK.
