StarCraft 2 map makers out there, Blizzard is watching. A thread popped up on the StarCraft 2 community forum in which a user named Cyrileo complained of his map being removed from Battle.net. According to Cyrileo, the mapped was deemed "inappropriate" by Blizzard and subsequently deleted. Further on in the thread, as reported by our cohorts at Big Download, Blizzard community manager Lylirra noted that all maps are "subject to review to ensure that they promote a fun and safe environment for all players." Should a map fail to meet these criteria, it will be deleted and the creator contacted.
The reason such moderation wasn't enacted in the first StarCraft, according to community manager Bashiok, was that Blizzard simply didn't have the staff. Things have changed this time around, so take note of Blizzard's official policy on inappropriate content: "Any content found to be offensive in nature has no place on Battle.net. Such content can be changed or removed, and the publisher warned or suspended." Bashiok noted further that Blizzard is working to improve the system, which will hopefully offer map makers more detailed reasons for removal in the future. As a general rule of thumb, we'd say avoid building maps shaped like wangs.
