When supplying their company with a Web filtering programme, the directors or managers of such companies often have sites of inappropriate content in mind. They wish to prevent their employees from engaging in disgraceful activities and save their business unwanted scandal. What they can easily forget is that the Internet offers much more temptations than only pornographic sites. There are numerous time-wasting websites such as Youtube, Facebook or MySpace which can attract users. Nowadays it has become quite common to set up accounts on different sites, have them connected and swap favourite videos and audios with your friends who have similar interests. Once you start engaging in such Internet activities, your involvement constantly grows up to a point when you log in every five minutes to see if there are any new messages for you. In such a situation it is very difficult to tear yourself away from your computer. No wonder that employees take advantage of the free access to the Internet at work. And not because it is a way of sending money, but because it is a habit or even an addiction. Company managers should therefore take into serious consideration banning any access to such popular sites by means of spam filter programmes.
