So I've been talking to a mate of mine who exploits the hell out of his telecom broadband package, he's on the 20GB plan and has figured out that telecom doesn't bother to slow you down until the day/day after you go over your cap. So he guns it on the last day of the billing cycle and uses anywhere between 60-90GB's (around 4 times his bandwidth limit) in one day. So my question is; is this practice wise/does anyone else do this on telecom or other ISP's slowdown plans, and the practice incur the wrath of the ISP overlords eventually?
