of people's web browsing, collecting the URLs of sites visited. The resulting profiles can potentially link with information that personally identifies the individual who did the browsing. Some web-oriented marketing-research organizations may use this practice legitimately, for example: in order to construct profiles of "typical internet users". Such profiles, which describe average trends of large groups of internet users rather than of actual individuals, can then prove useful for market analysis. Although the aggregate data does not constitute a privacy violation, some people believe that the initial profiling does. Profiling becomes a more contentious privacy issue when data-matching associates the profile of an individual with personally-identifiable information of the individual. Governments and organizations may set up honeypot websites – featuring controversial topics – with the purpose of attracting and tracking unwary people. This constitutes a potential danger for individuals. Flash cookies When some users choose to disable HTTP cookies to reduce privacy risks as noted, new types of cookies were invented: since cookies are advertisers' main way of targeting potential customers, and some customers were deleting cookies, some advertisers started to use persistent Flash cookies and zombie cookies. In a 2009 study, Flash cookies were found to be a popular mechanism for storing data on the top 100 most visited sites. Another 2011 study of social media found that, "Of the top 100 web sites, 31 had at least one overlap between HTTP and Flash cookies." However, modern browsers and anti-malware software can now block or detect and remove such cookies. Flash cookies, also known as local shared objects, work the same ways as normal cookies and are used by the Adobe Flash Player to store information at the user's computer. They exhibit a similar privacy risk as normal cookies, but are not as easily blocked, meaning that the option in most browsers to not accept cookies does not affect Flash cookies. One way to view and control them is with browser extensions or add-ons. Flash cookies are unlike HTTP cookies in a sense that they are not transferred from the client back to the server. Web browsers read and write these cookies and can track any data by web usage. Although browsers such as Internet Explorer 8 and Firefox 3 have added a "Privacy Browsing" setting, they still allow Flash cookies to track the user and operate fully. However, the Flash player browser plugin can be disabled or uninstalled,
