Human trafficking according to the following article is a huge business world wide to a tune of a 100 billion annually and it's expanding. This should be a big concern for families with children and young adults and every caring soul would expose any information leading to cacthing the criminals and saving the victims. This would include sharing information of the methods used by human traffickers in their crimes. Now these criminals are aware of the risks involved and don't want to get caught. They concentrate on vulnerable individuals that can be trapped out of the view and captured without anyone observing it. One method is to mark the car of such individual with a zip tie or something else that the victim would try to remove before entering his/her car. That gives the criminals some more time to capture the victim. Now this kind of news is vehemently denied in the links appearing in the search engines. While the idea of turning the victims attention away from the danger is totally worth of considering the fact checkers' denial confirms its veracity.
