This entire discussion is bizarre - adults worrying about whether people are spying on them and going to turn them in. If this were happening at a regular church, nobody would be worried about what someone else was doing.
It reminds me of the time my elder ex-husband asked me why I didn't stand for the prayer. I told him this was not Catholicism, so I didn't think we had a ritual. Later, I attended a Catholic Church, where there is a formal ritual, and people knelt, sat or stood as they saw fit, without anybody questioning their individual choice.
They (JW's) have people spying on you everywhere you go anyway, at least if any fellow dubs are around, so get over it. They spy. That's what they do. As is often said here, It's a CULT!
There's an easy solution, purrpurr. Look at non-JW websites away from the meetings, and you shouldn't have a problem and can have peace of mind at the meetings.
