Unlimited!!
My pet hate.
Way back when, I used Pipex for an ISP. They were the only one that advertised "Unlimited" bandwidth, I used to hammer the torrent sites so would frequently be transferring lots and lots of files. Every six months or so, I would get an email from Pipex saying I was exceeding their fair use policy, I replied with a link to the OED entry for unlimited and told them to get their lawyers to read up on it. Never heard back, not once, and never got cut off either.
Biting the hand that feeds IT
