Over the past few months I have had a series of "USERS" sign up with the same pattern of names and email addresses. They follow this pattern:
I am assuming this is some sort of hack attempt or something. The are all listed as user, none has hacked in as Admin.
To tell you the truth I have looked thru my site and in cannot find out where they are finding a command that lets them sign up as a user at all. (I am not a power user of WordPress obviously).
I DO use the Subscribe plug-in from Jetpack and have subscibers from that plug-in. But I don't understand what is happening with the USER sign up.
