Scammers sent out an email today purportedly from Pokemon Go app maker Nintendo and Niantic that announced it will begin to charge $12.99 a month to use the full version of the massively popular game to compensate for the “overwhelming response” and “the need for more powerful servers.” The game is currently the most-downloaded free app at Apple’s iTunes.

According to the email, Nintendo would “freeze accounts in 24 hours if users do not upgrade through the app store.” Several news outlets fell for the ruse initially (including this one — sorry about that).

The app has proven to be a huge success after being downloaded 7.5M times in the U.S. alone in under a week, prompting someone to try and cash in at least. Nintendo shares, which trade in Tokyo, appreciated 12.8% today. They’re up nearly 59% since Thursday.

Meanwhile, Sen. Al Franken (D-Minn.) today raised concerns about user information the game collects.

Pokemon Go’s privacy policy “suggests that Niantic can collect a broad swath of personal information from its players,” he says in a letter to John Hanke, the CEO of Niantic — a company that Google spun off last year that developed the game.

That data “can then be shared with [the app provider] and ‘third party service providers’… for a non-exhaustive list of purposes.” Franken asked several questions about the privacy policy, and protections, that he wants answered by August 12.
