2 accounts, 18 months, only one was logged on.

Well, I came back from the 6 month ban and started botting again, got hit with 18 months on today's wave.

I was logged in on the one account when it got hit, the second account I hadn't logged on in several days, so I suspect the detection was probably prior to today.

I was mostly using GarrisonBoss and Tanaan jungle questing, plus running old raids on various alts. Probably 6-7 hours a day total.
