Some blogs are seeing a new post that says "eeyore is cute!"
We are identifying the cause of the problem and are working on a fix.
Update: During routine testing, a bug caused a small number of FTP blogs to publish a test post. No systems or accounts were hacked. We have corrected the original bug, and are working to remove the test data from the blogs. In the meantime, republishing your FTP blog will also correct the problem. We apologize to those bloggers who were affected - we are looking at mechanisms to prevent similar occurrences in the future.
Note: Some users with non-FTP blogs who have opted to receive post confirmation emails may have seen a spurious email about a test "eeyore is cute!" post. This email can safely be ignored.
Update: This is now fixed.
