1. Hezi Cohen, a CFA candidate, is a heavy user of social networking sites on the Internet. His favorite site only allows a limited number of characters for each entry so he has learned to abbreviate everything, including CFA trademarks. Cohen also enjoys professional networking sites and contributes regularly to blogs that discuss the broad topical areas covered within the CFA Exam Program. In addition, he posts to these blogs pieces he has written in his area of expertise: retirement planning. By claiming to be an expert on retirement planning, he believes his stature within the investment community increases and he can gain more clients. Which Internet activity can Cohen most likely continue to be in compliance with the CFA Standards of Professional Conduct?
