They can disfellowship anyone, active or not, at any time. All they need is to attempt to "counsel" you for something they know is impossible to fully comply with. Then, after an unreasonably short period of time, they check up on you. This can involve buying expensive articles, and you do not have the money. Obviously, you are not likely to be in compliance. What they get you on is for not giving the hounders double honor, which they can translate as "brazen disregard for authority" or "loose conduct".
Another thing they can get you for "loose conduct" is conscience matters. So they told you not to listen to Journey. You still have a Journey CD a couple of days later, and they again call that "brazen disregard for authority". Never mind that you still have the CD because the garbage collection is another day or two later. Even if you are inactive, they could invent something, or attempt to contact you. Even stunts like interfering with your job is not off-limits to those cockroaches: They tell you that they need to talk now, and if you are too busy, "brazen disregard for authority".
