Test@test.com - Please Help!

A user registering as "test@test.com" keeps viewing page “/” on my site and other pages, according to Google Analytics, Segment, Mixpanel. All hours, all the time, and it’s been happening for months.

They also keep appearing in my list of users on these analytics sites. But they’ve never signed up on my website and do not show as a user in bubble data.

Is this a hacker or something? Or a test account through one of my analytics providers?

I’m sure this sounds idiotic but looking for some direction on this…

If it’s unwanted, can I block access to this account?
