I can't resist:
Oh, what a tangled Web we weave
When first we practice to deceive.

Leaving aside the anonymous bozo's suggested remedy, I meant to
highlight the fact that many on the Web are vulnerable to bad actors,
particularly when it is their own government enabling or even hiring
FLOSS Manuals (a name that is widely ridiculed; I didn't choose it) is
considering how to deal with this problem in its Circumvention manual,
How to Bypass Internet Censorship. This goes far beyond censorship, of
course. Anybody with useful knowledge is welcome to contribute.
Although I am one of the original authors of this book, and although I
found a math error in the original RSA paper on public-key
cryptography, I consider myself a technopeasant when it comes to
_practical_ issues of evading actors this bad in national governments.
Can Iran certify itself to Iranians as the operator of numerous Tor
Onion Routers? What does the Iranian circumventor do in this case?
PS Rick, thanks for reminding me to move my subscription.
