Comment (by phw):

 Thanks for this, antonela. Your scenarios should cover the majority of
 censorship scenarios that Tor users experience. All three scenarios
 however can result in the same kind of censorship, so from Alice's point
 of view it makes little difference if she's subject to on-device or to
 ISP-based blocking because the effect is the same. All three scenarios can
 result in the following:

 1. The domain torproject.org is blocked (user must use GetTor to get Tor
 Browser)
 2. Directory authorities are blocked (user must use bridges)
 3. Default bridges are blocked (user must use non-default bridges)
 4. Vanilla Tor is blocked by protocol (user must use obfs4 or snowflake)
 5. bridges.torproject.org is blocked (user must use moat)
 6. Google's STUN server is blocked (user must use something other than
 snowflake)

 All that said, here are two more scenarios, for the sake of completeness:

 * Self-censorship: fear of consequences may prevent users from learning
 about or using Tor Browser.
 * Throttling: In theory, an adversary could throttle (but not block) Tor
 traffic, in an attempt to discourage people from using it.

Comment (by antonela):

 **Scenarios**

 Based on [https://ssd.eff.org/en/module/understanding-and-circumventing-
 network-censorship](https://ssd.eff.org/en/module/understanding-and-
 circumventing-network-censorship)

 (1) Blocking or filtering on devices

 (2) Local network filtering

 - User cannot access to http://torproject.org to download Tor Browser

 This includes reaching

 - gettor.torproject.org
 Do we have a list of mirrors? can we have a list of mirrors? how
 users access to gettor information if the primary domain is blocked? can
 we optimize search engines to show trusted information?

 - bridges.torproject.org
 Do we have a list of mirrors?
 Should bridges.tpo have TPI branding? should bridges.tpo live
 under www maintenance?

 - torproject.org/download
 Do we have trusted distributors? are app stores up-to-date?

 (3) Blocking or filtering by Internet Service Providers (ISPs)
 - User cannot connect to the Tor network

 Which scenario is missing? What use case is not contemplated?
