This revelation could hurt Spotify’s shares as the company prepares for its direct listing on the NYSE next month.
In Spotify’s recent SEC filing, the firm reveals around 2 million free-tier users bypassing ads.
“On March 21, 2018, we detected instances of approximately two million users as of December 31, 2017, who have been suppressing advertisements without payment.”
Spotify has since started to disable the app, along with a notification that reads:
“We detected abnormal activity on the app you are using so we have disabled it… 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.”
The notification ends with a warning, “If we detect the repeated use of unauthorized apps in violation of our terms, we reserve all rights, including suspending or terminating your account.”
According to Spotify, the firm’s paid subscriber base is increasing steadily, from 30 million paid subscribers in March 2015, to 70 million in January this year.
However, as Spotify explains, they have previously included users using adblockers in their key performance indicators.
The incident forced Spotify to reduce its monthly active user count from 159 million to 157 million total in 2017.
Spotify further highlighted that it currently did not have the data to adjust previously provided key performance indicators due to which certain metrics may be overstated in its prospectus.
Spotify recently announced it would be rolling out its self-serve ad platform to marketers in the UK and Canada after a successful launch in the US last year.
