QR code scanning of emails from bridges@torproject.org

Getting bridges by email instead of Moat might be a valid option when Moat doesn't work for some reason. I'm not sure how possible it is for a censor to block Moat since it uses Meek in the backend.

Bridges over email can be very useful anyway until we have Moat.

Typing obfs4 bridges inside Tails is a nightmare as they are very long:

obfs4 107.161.172.100:8080 401E5912C821FBB913D2BD89368C246A241C0512 cert=avfemQzJey18ZvPrTjpE86PbZR2gsf0nJsC/HabjtKoLV4ip6RVR6FRGMQnnszsrhQm3RA iat-mode=0
obfs4 185.220.101.156:12346 26AE211EB6EF3D10D13436884029D1CC236F3582 cert=p9L6+25s8bnfkye1ZxFeAE4mAGY7DH4Gaj7dxngIIzP9BtqrHHwZXdjMK0RVIQ34C7aqZw iat-mode=0
obfs4 80.71.46.55:18462 05BFD8CE8C66BED061E4268A55D82C966DED051E cert=g6JJOZggoTukko23appohuA9jBNlahdaSBHb11xwGmtkNU4A4QOXO4Yup+Pd/UX91do/cg iat-mode=0

We could allow users to scan a QR code within Tails to copy bridges obtained by email on their phone for example.

Also, right now the captchas of Moat are not accessible: https://gitlab.torproject.org/tpo/anti-censorship/bridgedb/-/issues/10831.

I wonder whether scanning the QR might provide a viable alternative for blind people until then if it has good UX.

I managed to scan the (pretty big) QR code from bridges.torproject.org from my phone into Tails using zbarcam.
