Thank you for all the feedback you’ve given us so far.
We want to let you know that we take both account security and the artificial manipulation of streaming activity on our service extremely seriously. We also would like to highlight some of the actions that @Eversome pointed out should be taken if that is indeed the case.
Spotify employs multiple detection measures to monitor consumption on the service in order to investigate such activity and we continue to refine those processes. Part of this are email notifications we send to users every time a new login has been detected, as described by @Eversome. Just recently we also ran a test that would prevent usage if an email wasn't verified as part of our continuous efforts to improve security.
As with any measure that could lead to legitimate account holders losing access to a service, we need to do our due diligence with rigorous testing to ensure there are as little friction or inconvenience as possible. For the time being, besides the mentioned notifications, we have built and provided tools in place that can help you quickly resolve an issue by yourself. Our support team will of course also be happy to assist you in regaining full control over your account. We also strive to provide information on how to protect your Spotify account. In both instances we try and raise awareness of the third party apps that @Eversome also mentions.
Regarding unauthorized streams, there are actually consequences of those and we utilize both technical and manual measures to monitor activity and action is taken, again just as @Eversome correctly states should be done. If you ever come across any suspicious activity on Spotify, reach out to our support team and make sure to report it so it can be investigated.
We realize this thread is gone a bit off topic with lots of questions in one place and some speculation of what is and is not done being mixed with it all. It’s for this reason we’re going to lock the thread. Since the best way for us to gather your feedback is via the Idea Exchange with one thread for each topic we suggest having a look at this idea. Check out this article for more info on how ideas work.
