Weird subscriber showing up in Users?

[CherylMcL]

OK. This is a new one. On this one blog that is a new redesign, www.barbarafalconernewhall.com, I have email subscriptions being handled by MailChimp.

Twice, now, a dutch Subscriber has shown up on the Users screen, yet, when I look at site statistics, there isn't a subscriber listed. It's only in the Users section. Wondering if this is due to hacking or some other nefarious activity?

Subscriber email: vakantiehuis@het-vakantiehuis-oostenrijk.nl

We've eliminated the admin User. Any thoughts? We deleted the previous one and now there's a return. Gremlins?
Many thanks.

it might be a hack, you should try this service for a basic scan

Thanks, Nick. I just had it scanned and it comes up clean though I need to upgrade it. Hmmm. Strange how it shows up as one of the Users!

Make sure you do all of your upgrades

Thanks. Will do.
