The list I posted earlier (October 12, 2003) was compiled around 3Q 2002 but when I checked the list recently, I discovered that some of the sites that used to be blocked were now unblocked. SCV also changed its proxy server so my old xch script didn't work any more.

Specifically, before I could just check the HTTP-header to see whether a file was blocked (Error 403 Forbidden). Now, the header that comes back is OK, but the server actually sends back a page that says the URL has been blocked. That means that we have to ask curl to retrieve the whole web page before we can tell if it has been blacklisted. Consumes a lot more bandwidth.

Anyway, a lot of the sites on the old blacklist are not blacklisted anymore. Only 26 out of the original 59 sites are still blocked. Reason unknown. No obvious pattern for what's in or out.

Rot13'd as usual (See Oct12 post for decoders) :

Are any of the sites on my challenge list now blocked that were not blocked before ? Don't know. I'm reluctanct to re-run the test completely because the change in SCV proxy's response means that I would have to actually retrieve entire web pages instead of just headers a few thousand times.

Did find a few new sites by doing variations of the original 59-site list. Just tacked on a variety of country-code TLDs and challenged the proxy again, e.g. www.playboy.com becomes www.playboy.com.hk, .tw, .au, .co.jp etc.

This gave a few more sites:

(.nh = .au and .gj = .tw)
