You appear to have missed the point. The original premise put forward was that there is no completely legal way to chew through the vast amounts of data being claimed. I mentioned MJ12 to show that there is. Whether or not it is a reasonable thing to do on a home connection is irrelevant as is whether or not it's against ISP T&C the point is that it is 100% legal.
Of course the most likely reason for consuming terabytes of data is that copyright infringing video data downloading and streaming is taking place.
As it happens the one time I did run the MJ12 crawler was to "persuade" the ISP that I really wasn't the sort of customer they needed and t releaseme 3 months early (there wereother grounds too concerning their shoddy implementation of the IWF filter which blocked more than it should at times including some of my backups) although in truth it was more their new customer pricing that annoyed me.
