The SEC does not like insiders chatting on forums with the public. However, I've yet to see any law or regulation forbidding them from doing so or even running their own forums. It's possible Glenn may have suggested they shut it down. If he were really deciding things, don't you think he would stop Melvin and even Urbie from visiting Sterling's chatroom? There isn't much of a difference between a forum and chatroom except the latter one normally doesn't have a written trail of what everyone says.
