Wait, I'm still stuck on this:

Nevertheless - I (some how) ended up with a subscription (I've never subscribed or paid for it)
Because that happened to me, too, except I never got an actual magazine ... just a bunch of bills, and then a collections agency bugging me. I paid the damn thing but have still never seen the magazine.

Not that I want to, after reading this thread, but I'm just a little surprised to find out that it's not only me getting mysterious subscriptions I didn't ask for.
