== Discussion ==

https://www.reddit.com/r/TOR/comments/kj7git/is_bamsoftwarecom_related_to_th...

Malwarebytes apparently blocks snowflake.bamsoftware.com and snowflake-broker.bamsoftware.com.

But this should not have happened since https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowf... (webext-0.0.6), which changed *.bamsoftware.com to *.freehaven.net? https://gitweb.torproject.org/pluggable-transports/snowflake.git/commit/?id=...

How did this user get a copy of the browser extension that still contacts these old domains?

Pick a reading for the next reading group discussion
