People who access Spotify using hacked apps that remove some of the restrictions placed on free accounts are receiving warning emails from the company. Noting that "abnormal activity" has been observed from the user's software, Spotify warns that future breaches could result in suspension or even termination of a user's account. TorrentFreak reports: "We detected abnormal activity on the app you are using so we have disabled it. Don't worry -- your Spotify account is safe," the email from Spotify reads. "To access your Spotify account, simply uninstall any unauthorized or modified version of Spotify and download and install the Spotify app from the official Google Play Store. If you need more help, please see our support article on Reinstalling Spotify." While the email signs off with a note thanking the recipient for being a Spotify user, there is also a warning. "If we detect repeated use of unauthorized apps in violation of our terms, we reserve all rights, including suspending or terminating your account," Spotify writes.
