----------
Thanks to a new Pluggable Transport called Snowflake you can now help censored users access the Tor network by just installing an addon. The way it works is pretty simple: censored users learn about a temporary proxy (a 'snowflake') from a broker (using domain fronting or other techniques) that they establish a connection with using WebRTC, the temporary proxy then transmits the requests to a bridge which then connects to the Tor network, the temporary proxy thus functions as a middle point between the censored user and the bridge <=> Tor network. The idea is that by getting a significantly large number of ever changing and decaying temporary proxies it will be hard for a single censor to keep track and block all of them.
As explained earlier, when you function as a snowflake proxy no exit traffic is generated at your level, you just transit traffic to a bridge which then connects to the Tor network. Hence there is no need to worry about which websites the clients are accessing through your proxy. Their visible browsing IP address will match their Tor exit node, not yours. In addition Snowflake's strength comes from having a large pool of temporary proxies, so don't forget to spread the word and have a maximum of people installing this addon!
