I tried to submit the official Wordpress.org announcement and got "stop spamming us".

Is Wordpress.org domain banned on HN?
Maybe some wordpress.com blogs were being used for spam but wordpress.com != wordpress.org
wordpress.com is the blog hosting site
There are some worthy blogs that could be linked here from wordpress.com, but even if it had to be blacklisted, wordpress.org should not be, there shouldn't be third-party content on it except for maybe the forums.
