It just occurred to me that if a person either wished to avoid having to continue in a position such as ministerial servant, pioneer, "sound guy" etc etc a good way to get out of this, and generally become "less useful" to the society & cong would be to refuse to allow JW.org to store your data.
Naturally your loyalty will be questioned, but you can simply say you fear your data falling into the "wrong hands such as the state during the great tribulation", since your address, telephone number and many other particulars are stored on the new publisher I.D. system.
JW.Org has been ramping up the fear lately, broadcasting videos portraying persecution and publishing articles about arrests and torture in Russia.
It's the perfect time to 'slip the noose', citing data protection issues, as a way to become less active in the congregation without sparking anything but the (useful) suspicion that you may be becoming a little 'loopy'.
