Seems Legit: App Store Support Spam
Yet another round of spam purporting from “App Store Support” or “App Store Team”, complete with graphics directly linked from Apple’s own server.
Based on a few reports, this type of spam started making the round on Thursday, October 8, 2015. Anecdotally, all the reports come from users with mac.com emails.
