That would only be true if they actually allowed people to post without having to have a moderator approve it. Talk about censorship let alone crappy bug support.
You are allowed to post, but the anti-spam feature is very sensitive to lots of links and/or IP's used by known spammers. If you are tagged for moderation you are meeting one of these criterias. If you keep on having problems with it, PM me a link and I'll see what I can do to help you bypass the filter.
