I know that I am such a small fish in such a big pond. I am not that worried about it.
I don't openly violate their rules as far as they know, but I meet with ex-JW's all the time. Heck, I used to organize the local meetups.
I won't, however, allow a single solitary active JW into my Facebook friends. They have asked from time to time. That way, I can be myself.
I still have not run across any ex-JW's that I knew when they were JW's. I hope to, one day.
