#6180: Detecting censorship in HTTP pages

Comment(by hellais):
We discussed a lot about this during the OONI hackfest with mct and this
is what we talked about:
We can divide the possible approaches for distinguishing a blocked page
from the correct result page into two categories: Statistical and
Heuristics.
# Statistical approach
- Bayesian
- SVM
- Fuzzy signature matching
- Other classifiers
What we want to do is run these classifiers on the corpus of block pages
and real website.
# Heuristics
- List of regexp that apply to censorship pages
We also talked about having clients tell the backend what it got as a
response and having the backend figure out if such a page should be a
block page or the correct result.
