We have [https://collector.torproject.org/archive/bridgedb-metrics/
BridgeDB usage metrics] that allow us to infer where our HTTPS frontend
works and probably doesn't work. This is not as easy for email and for
moat because we currently don't see the source address of a client (see
#32276).
Emma however can tell us if a user can use each of BridgeDB's distribution
mechanisms:
1. It checks if the page behind https://bridges.torproject.org contains
the string "The Tor Project" (for the HTTPS distributor).
2. It checks if the page behind https://ajax.aspnetcdn.com contains the
string "Microsoft Ajax Content Delivery Network" (for the moat
distributor).
3. It checks if the page behind https://accounts.google.com/ServiceLogin
contains the string "Sign in" (for the email distributor).
4. It checks if the page behind https://mail.riseup.net/rc/ contains the
string "Welcome to mail.riseup.net" (also for the email distributor).
What remains is to ask volunteers in different countries to run emma, so
we can get a better idea of where our distribution mechanisms (don't)
work.
