The Jws I know are less likely to make much use of the Internet.
One ex-JW I know was threatened by her JW daughter & JW elder-son-in-law who threatened to take away her computer. They thought mom was spending too much time on it, chatting with worldly folks. She threw the two JDubs out of the house and reminded that she was a grown woman and knew how to conduct herself. After that, she became an ex-JW.
Another current JW works with computers. Got a tablet, uses it to download magazines & books of interest. But, rarely surfs the Internet for knowledge or communication with others. Does have a Facebook account, but rarely posts.
Another current elderlly JW has a computer, a laptop. Always into technology. But, would NEVER go on a site like this. Probably would take a shower if he bumped onone page by accident.
