Question about Youtube subscriptions

[Beatlelvr]

I just had to unsubscribe to about 25 channels I never subscribed to! Question: how did they get into my subscribed list to begin with?
Don't tell me " you must have done it and forgotten." Most of them I NEVER would have subscribed to. Anyone else have this problem? Thanks.

1. I've noticed the same thing recently

Not as many channels as you had to deal with but maybe one or two a week. No idea how it’s happening and interested in any answers folks may have.

3. Malware, a breached Google account and phone apps can all do this.

4. If an app is in Google's Play Store, don't they have to be free of such malware?

Or is it hidden within the terms of the app somewhere that says you agree to the app subscribing to channels in YT?

5. They are supposed to be free of malware.

However, the Bad Guys know that Google and Apple cannot police all the apps in a timely manner.
