Are you referring also to Columbia House and BMG in the 90s? Sign up, get seven CDs for a buck, then you forget to cancel and they send you "A Barry Manilow and Kenny G Christmas" for $18 plus S&H.

This still happens online with an X-day trial of something, fine print says to cancel or be charged $XX.XX/mo. Good luck figuring out how to cancel, though.

The key phrase here is sign up. I can't just send you an unsolicited text message subscribing you to Cat Facts (only $29.99/month!) unless you follow my intricate opt-out scheme.

Yes, this is what I remember my parents getting really mad about as a teenager. This was one of the first times in my life I thought to myself "People do this kind of thing to other people? WTF humans."
