In 1998 my neighbor and wife were being visited by jdubs, in fact the wife's mother and step farther were jdubs. He husband asked me about jdubs as he knew I presently was one. Over time, I enlightened him as to the true purpose of their visits (recruitment) rather than a bible study. Told him when they come again insist on just the Bible, I let him know how they would start controlling his and his families lives. How he would slowly be sucked into the organization. I showed him the magazines (older ones) and how their doctrines change, and how they had caused the needless deaths of many through their adherence to doctrinal issues. I then told him what would happen after he was baptized and disagreed with them that they would insist that he believe them, the governing body etc. After several months of me and him getting together going over the Bible their supposed 1914 date, desgtruction of Jerusalem in 607 vs 587/6 BC. He had begun doing some research on his own and decided that he and his family were not going to have anything to do with them. When his mother in law visited almost 8 monhts later, his wife told her they no longer study and it was because of the information I had given them about the witnesses.
Her mother spoke with her husband and they decided that he should call Bethel and complain about me, I never heard anything from the local congregation about it one way or the other. He still thanks me to this day when we see each other for giving him the needed information he used to ask them questions which put them on the spot. He was able to catch them in many lies about what the witnesses did and didn't believe. They wanted him to question his church but they sure didn't like it when he asked them pointed questions. Thankfully I was able to help him to have nothing to do with them. His wife was a little pissed at me as I am sure she heard talk from her mom over the issue and how good the witnesses were. The upshot of it was that either he nor his wife had anything to do with them after deciding they lied to him on many occasions.
I felt heartened over the experience and glad I was able to give them info so that they wouldn't be sucked in to the quagmire of the witnesses.
