I know JW's who haven't come near a Kingdom Hall or picked up a WBTS publication in years. Some of them moved away to different congregations and simply stopped attending, others didn't move away but simply stopped too. As far as I know only a couple of them ever got Df'd.
The ones who got away with it though were either single or had spouses who felt the same way. It seems having a devouted significant other makes fading a lot more difficult.
