Facebook Partners With Web Of Trust To Block Malicious Links
Mark my words, this won't end well. I used to use WOT and thought it was a good idea, until a smaller number of its users hijacked the system to give sites they didn't like a bad name.
In the end its just a different form of censorship, and we know that doesn't work well for any kind of genuine freedom.
If you use WOT, do yourself a favour and give it the flick!
