Over the last several days, we've been seeing a novel trolling attack on Super User: a flood of answers containing plagiarized content posted by a user called "Marlin Woods":

[![Marlin Woods flagged posts][1]][1]

The user creates a new account for every post; however, the same Gravatar is used so it's apparent that it's coming from email address and hence the same person. Because the accounts are unregistered, they do not show up in the Users page under **new users** > **creation date**.

Can we get someone to stop this ASAP?
