I have recently started using WordPress and I love it! However, I have two posts that are currently protected and today someone posted a comment on both of them. No one should know the password (same password for both posts). Both comments contained references the post, so I know the visitor actually read it, too. They were rude and obnoxious comments, so they're now deleted. Are protected posts really that insecure? How can I fix it so my proteted posts aren't hacked again somehow and read by the wong people?
