Well, I believe this is true because I see my JW mother every once in a while when I visit my dad and she has been more shunning than usual. (She swallows every line of the Watchtower without asking)
Also, my JW brother suddenly cut me off completely without warning. We were supposed to meet at a bar and go to a gun show and he never responded.
It would make sense that they are feeling a lot of pressure to be extra careful as regards former members.
