Thanks for replying! I get that hacker 15 message a lot. For example, if someone registers the name Ann it may say Hack attempt for Mergutrann if I look her up and a bot had already registered a similar name prior. She would be able to register, but I would not be able to pull up her name and approve the registration. I never just click on the notification link and approve anyone until I look them up manually first, so I won't get stuck with people I can't ban. I'm used to it and not worried about the hacker thing. I just need to delete this one User. But I'm not confident about how to do it.
