To keep with the times the Planet Team has slightly tweaked our policies regarding notification of blog owners if their blog is removed to allow for things other than filing bugs since not everyone is reading bugmail, especially if they leave the project. To quote the changed item:
Blogs can be pulled from Planet for poor availability (generally over a week of being unavailable). The blog owner will be notified by a bug being filed, email, IRC, IM, or other communication means identifying the feed so that they can either fix their issue and be re-included or choose to be removed from Planet permanently. When removing a blog if a bug isn’t filed, a commit message will indicate the action taken (notified on IRC, Twitter, etc.).
