http://www.techpolicy.com/FlashCookiesPrivacyII.aspx In 2009, my team at Berkeley showed that many top websites were tracking users through Flash cookies, and that some advertising networks were "respawning" or reinstantiating HTTP cookies that the user deleted. Over the past two years, a chorus of advocates, regulators, and businesses condemned the practice of using Flash for unique user tracking. This chorus was heard by many. In our followup survey of Flash cookie practices, we found that fewer websites were using Flash cookies. Thirty-seven of the top 100 websites were doing so, down from 54 in 2009.

There, people exchange highly personal stories about their emotional disorders, ranging from bipolar disease to a desire to cut themselves. It was a break-in. A new member of the site, using sophisticated software, was "scraping," or copying, every single message off PatientsLikeMe's private online forums.
