Hi Clodo,

Thank you for your interest in OONI.

Do you have the code published somewhere?

It was quite difficult to find out and interpret the results from
[1] could you maybe provide some pointers?

How did you find out about these domains and why do you think that they
contain CP?

In any case it would be very interesting to see these results or
of the ones that can be made public.

It will be very interesting to instruct the probe software submit
results to an ooni backend [2]. In any case the probe software can
maybe even written as an ooniprobe test [3].

I don't think that is all about CP only.
Right now there are so many blacklists and censored websites worldwide
and as far as I know people are interested in finding out of what
resources are being blocked. Many of these started blocking
gambling related websites and later added a bunch of other
websites hence opening the door for censorship and blocking of other
websites at will [4], [5].
