I received the same message about 4 hours ago. There have been some major breaches and user databases from many websites have been published.
Over 770 million email addresses shared online in largest data breach in history
I checked my email adress on the site https://haveibeenpwned.com/ and it is found in databases "Anti Public Combo List" and "Onliner Spambot". Perhaps one of those includes the storagereviews user data.
