Wordfence: “You keep on knockin’ but you can’t come in”

Here’s a little something to listen to while you read this post. It’s appropriate for this post.

Wordfence is effectively blocking blocking attempts to log in using invalid usernames. Refer to the post WordPress Plugin: Wordfence logging lots of failed login attempts for further details. However, there’s someone sneaky who is quietly trying to log in using a valid username.
