When we look back at 2010, one of the things we’ll remember is how ubiquitous social became online. Facebook exploded, Twitter grew up, people “checked in”, and almost every website seemed to develop some sort of social component.

Not surprisingly, people using OpenDNS — parents, IT administrators, sysadmins, district technology heads — noticed the same thing. Data collected on how people used Web content filtering in 2010 shows this fact: Facebook is the #1 most blacklisted site. And interestingly enough, it’s also the #2 most whitelisted site. Other sites that were frequently blocked include MySpace and YouTube.

Not surprisingly, Facebook was also a frequent target of online scammers. When we analyzed submissions to Phishtank in 2010, we saw that Facebook was the second most frequent website targeted by phishing websites. The #1 target for 2010 — and throughout every month of the year — was PayPal. PayPal accounts for an incredible 45 percent of all online phishes.

These statistics and more can be found in a report we’re publishing today, all about the Web content filtering and phishing data we saw in 2010. I encourage you to download it and read through it. There’s some fascinating information included in the report, including which sites are the most frequent target of online scammers, how businesses are filtering content, and what categories people most frequently block on their networks.
