Is this legit?

Got another one today, is this legit or is it a phishing scam?

I just got one this morning.

Me too. Strange.

I just got one..

I did as well. Any word what this is?

I got one as well, haven't visited this site in years. Didn't click on it but reset my password just in case. At least it got me back and looking around.

Any updates on this? I received one & deleted it.
