A revengeful elder gets hold of the passcode.
No longer complicated for him to keep track of someone like myself, gone since 1977, but am the other grandfather who has never even met the grandchildren. Perfect scenario for the revengeful one.
Or the less than honest owner of a janitor company who also happens be a prominent elder. He fires a recently DFd employee (in order to keep his staff clean of apostasy), then latches onto the ex-employees WT record and hacks some changes -- introduces some phoney pedophile charges and our friend, the exJW, is now smeared forever.
