"The level moderation process is something we're continually improving," said Valledor. "The small percentage of levels moderated have been done so after the community has reported them using the Good Grief tool. We never moderate levels that have not been reported in this way."

Reports of moderators deleting levels that contained no objectionable or copyright-infringing material have been consistent since the game's release in late October. Sony responded to the allegations by issuing a set of content guidelines for level creators to follow.

"The vast majority of moderated levels were due to offensive material," added Valledor. "However we are evolving the way moderation happens to ensure that creators are made aware of why their level was blocked. More to come shortly."

Valledor also noted the team is working to improve the game's online servers, as well as the search function for user-created levels.
