Some experts maintain that casinos in general arrange for self-exclusion programs as a public relations measure without actually helping those with problem gambling issues. A campaign of this type "deflects attention away from problematic products and industries," according to Natasha Dow Schull, a cultural anthropologist at New York University and author of the book "Addiction by Design." Other experts believe that self-enforcement is part of the problem gambler's own responsibility, as one aspect of any therapy program. "Without such acceptance of responsibility, much of the effectiveness of self-exclusion programs would be lost", as one explained.
