How is it that 9.9.9.9 comes to be listed as a snowflake proxy? Is the Quad9 DNS resolver really running a snowflake proxy, or is there some bug in the collection script?

Do you have an estimate of how complete the coverage is of bridges? In other words, if a censor were to block all these IP addresses, would it be effective? How frequently would the list have to be updated?

Have you read https://censorbib.nymity.ch/#Matic2017a? How would you say this effort compares? What recommendations do you have, to make bridges harder to enumerate?

What is the difference between “bridges-obfs4” and “bridges-obfs4-guards”? Is the latter obfs4 bridges that are also normal relays that have the Guard flag?
