More diverse domain tests.

[indolering]

Your list is fairly weak, it doesn't check a large category of sites.

If you are only interested in sneaky redirects, I would suggest adding www.torproject.org and an online bitcoin wallet. I'm not sure which ones might be using anycast, but blockchain.info has been the subject of MITM attacks.

File-sharing, porn, and gambling are subject to regular blocking. The following are popular targets and should be fairly stable:

• torrentz.eu
• 4shared.com
• xxx.com
• adultfriendfinder.com
• casino.com ?
• khilafah.net
• www.hizb-ut-tahrir.org

casino.com is an obvious target, but I had a hard time finding confirmed censorship of the site. I'm didn't find active blocks of torrentz.eu, but it's hard to find a stable p2p domain to test against. Everything else has been confirmed as an active target. Note that you should test for BOTH samples, as many places block one but not the other.
