staff:

This morning, some of you may have noticed a spam post appearing repeatedly on your Dashboard and on the blogs of a few thousand affected accounts. We quickly identified the source, removed the posts, and restored service to normal.

No accounts have been compromised, and you don’t need to take any further action.

Our sincere apologies for the inconvenience. As always, we are going to great lengths to make sure this type of abuse does not happen again.
