I think it's all fraud, but at the other hand:
In a Trump and fake news dominated world, and some "Unruhe" in many country's due to increased populism, there is a market for jw.org
The big solution just around the corner, that's what our grandparants, parants of ourself, once took for real. So a increase of the population JW's can be real.
Lets be fare, give them all a nice time in jw.org, some place in the world, to be respected.
It's not our purpose to judge about them, let's focus on our own life. There is some progress to make, when I watch myself. To be a better person, in family life, in social life.
