The Top 9 Websites Blacklisted In 2010 Ranked By OpenDNS
share this story
While examining customer data from home, school and business networks, OpenDNS researchers noticed that many networks restricted access to similar types of content. For example, certain popular websites frequently appeared on "blacklists" created by different networks. "Blacklists," as explained by OpenDNS, "are typically used when there is no desire to block an entire category [of content] in principle, but there is a focus on preventing traffic to specific websites based on a combination of their popularity and content."
Based on these findings, OpenDNS compiled a list of the top blacklisted websites. "This [...] list suggests a concern with the use of bandwidth by streaming sites and with privacy concerns from advertising networks." Some of the most-blocked sites include social networks, video streaming sites, file-sharing networks, advertising sites, pornography sites and more.
Take a look through the top blacklisted sites, and tell us (in the comments) if you are surprised by any of OpenDNS's findings. Do you think networks are justified in blocking sites like these?
