Comment(by hellais):

 I wrote up the HTTP Scan test:
 https://trac.torproject.org/projects/tor/wiki/doc/OONI/Tests/HTTPScan.

 The open questions of the HTTP Host scan apply also to this test. How do
 we verify in an efficient manner that a certain site is being blocked?

 The naive way to do so is to make a connection over Tor and check if that
 matches the one that is made over the live network, this has some problems
 though, for example if the site is geolocalized it will be different for
 Tor.

 Another simple approach is to have a database of content lengths of
 websites, but this also will fail if the censored page is very similar to
 the real web page.

 Another approach is to find a smart fuzzy matching algorithm for the Test
 page.

 This issue probably deserves it's own ticket here: #6180
