Companies use shock marketing to convince people to spend money they otherwise would not spend. They should not be allowed to use these marketing tactics without restriction. Furthermore, people are vulnerable and should not be exposed to these strategies. The use of shock marketing should be band from print and other forms of media communications.
Shock marketing tactics should not be made illegal. There is no good reason to ban them because this type of marketing is protected under free speech. If you don't like the marketing, you don't have to watch. It is as simple as that. Free speech is already under attack, leave shock marketing alone!
