As I recall, "marking" a person was another blunder of the Watchtower Society. As usual, when the Watchtower article addressed this subject Jehovah's Witnesses went "overboard" in its application. I remember people going up to others telling them that they were being marked for some perceived infraction. It started to create a lot of problems in the congregations since it was dividing "brother against brother." I think the Watchtower eventually addressed this problem by making adjustments in the application of scripture.
Over the years, the Watchtower got itself into a number of problems because of articles that were published. Remember the articles on "pornea" and sexual practices of married couples? The Watchtower Society was deluged with mail and phone calls. It finally decided to get out of the sexual counselling business and out of people's bedrooms and leave it up to the "consciences of individuals."
