Hi, I seriously disagree with your edits here and here. There is nothing wrong with providing *.onion links for websites, which officially support onion routing. If you don't know what does this mean, please read .onion. If you don't want to see such kind of links in templates and queries, set rank to deprecated (which I did for Facebook).
Disclaimer: my provider have blocked Facebook and various torrent websites. It also have blocked Wikipedia for few days; luckily the society response helped to stop such unthinkable act of censorship.
