Through Spotify's "freemium" service model, users have access to basic features without paying a subscription.
This includes shuffle-only play, and periodic advertisements.
By subscribing, around US$9.99 per month for a single user, a person can listen ad-free, among other perks.
But, some users have figured out how to work around this model, using so-called hacked aps to access the premium features.
Spotify has been criticized in the past for what seemed, to many, as turning a blind eye to the use of hacked software, which allowed users to access subscription perks without paying.
But, at the beginning of this month, it appeared the firm was tightening its grip.
As reported by TorrentFreak, some Spotify users have begun to receive emails from the company warning them about "abnormal activity" linked to their accounts.
In an email sent to offenders, a spokesman for Spotify said: "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 continues.
"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.
"If we detect repeated use of unauthorized apps in violation of our terms, we reserve all rights, including suspending or terminating your account."
