Facebook group postings allow "spying" on readers http://j.mp/MTN5fx (L.A. Times) "Facebook has introduced a feature on its Group pages that lets users see which other users have viewed their posts. The feature, introduced earlier this week, adds a "Seen by" tag to posts that users can hover over to see the reach of each post in Group pages. Based on a screen shot provided by Facebook, the features appears to already be on both its website and mobile apps." - - - This actually dates to mid-July. If there's a way to disable it so that you can view a group posting without revealing both your identity and the date/time of your access, I don't know what it is. Such a feature is bad enough on its face, but if it cannot be disabled it is worse. One might argue that membership in a Facebook "group" reasonably entails exposing to the posting party whether or not you have seen the associated messages, and when. But it's also clear that trust level varies widely among these groups, and if -- as the author of this piece speculates -- this is a move toward more general use of such exposure on Facebook beyond Facebook groups (such as recently implemented by Quora) this could become a very serious situation, very quickly. --Lauren-- Lauren Weinstein (lauren@vortex.com): http://www.vortex.com/lauren Co-Founder: People For Internet Responsibility: http://www.pfir.org/pfir-info Founder: - Network Neutrality Squad: http://www.nnsquad.org - PRIVACY Forum: http://www.vortex.com/privacy-info - Data Wisdom Explorers League: http://www.dwel.org - Global Coalition for Transparent Internet Performance: http://www.gctip.org Member: ACM Committee on Computers and Public Policy Lauren's Blog: http://lauren.vortex.com Google+: http://vortex.com/g+lauren / Twitter: http://vortex.com/t-lauren Tel: +1 (818) 225-2800 / Skype: vortex.com _______________________________________________ nnsquad mailing list http://lists.nnsquad.org/mailman/listinfo/nnsquad
