To the OP. You are not paranoid, and everyone posting on this forum, or anywhere online, should be aware that except for emails (which can also be hacked), your words are public.
If someone is looking to catch you up, whether it's a spouse, other family member, 'friend' or elder - they will be reading the exJW forums, reddit, etc. When a JW or JC wants to catch someone, we all know they have neither scruples nor boundaries (personal and / or legal).
Others have outed themselves by revealing too much personal information in their comments, in spite of repeated reminders by Simon to all of us, that the internet is not private.
Hope all is well. xx
