Warning to all those tethering with root.

So, today I woke up to a lovely text from T-Mobile warning that I have concealed tether usage data. The transcript of the text follows:

Regarding my tethering usage, I've only used a good 2GB extra than the mobile Hotspot allows. So, their idea of significantly exceeded seems pretty strict. So, even if you don't think you fall into the "percentile" of that one person using 2TB, to T-Mobile, you do. I'd still like to see them try to move me down to a lower plan though. I'll just leave and go to something like sprint.

So, I recommend being extremely careful. I have no idea how they detected it, but they are.
