I always hated the term unlimited when it's not really unlimited. Is it really abuse if you're using it as intended?
Edit: I eat my words. People are assholes. I thought this was referring to providers of unlimited storage or bandwidth, only to say "oh, you've using it too much, so we're going to throttle you."
I just want to add a surprising fact. My mobile carrier does actually deliver on the promise of unlimited data, and an ISP is the last company that I would trust.
I can try it, but my current record s 50 GB in a singled day. The only thing that it wants is a conformation via SMS for every 18 or so GB, but that is only if you use that much in a single day.
