The peer reviews of this week's reading group paper are public:
https://openreview.net/forum?id=7024czziih
I hadn't known it before, but peer reviews are public for all ACM WWW accepted papers: https://www2024.thewebconf.org/calls/research-tracks/ "By submitting paper(s) to The Web Conference 2024, the authors agree that the reviews, meta-reviews, and discussions will be made public in OpenReview for all accepted papers."
You can see the reviewers' brief written summaries, and reviewer adPJ raising the possibility that VPN detection could "amplify censorship attempts which are rampant on the web today especially by authoritarian governments".
While it was still a submission, the system was apparently called "VPNSniffer" rather than "VPNChecker".
