If the terms change, they contact you that they changed. At that point, yeah, you’re bound by new terms if you continue using the service. That’s kind of been the way things have been since the advent of Internet services in general.

I’m curious how you’re certain they defaulted first when you state that you never read the document in the first place.

>I’m curious how you’re certain they defaulted.

I'm sorry that was sarcasm. I didn't make any assumptions I just clicked the box or button or whatever.

Do they contact you? Most terms of service just say 'revisit here constantly in case we changed something'

I used Spotify during a Sprint promo (when they were my carrier way back when). At one point, I received an email stating that an update to the terms was made. I imagine they still do this, but I guess they could just as easily have stopped, not certain.

A lot of services that I’ve signed up with will announce new terms either via email (quick search of my email lists the most recent ones as Papa Johns, PlayStation, Disney Movie Rewards, Skype, Gamestop) or on next launch of app (Blizzard and Steam being prominent ones off the top of my head). I don’t know many that announce they will in advance though (ie at sign up saying they’ll communicate changes to you), so probably better to be proactive than reactive? I don’t know.
