Maybe it's just me, but all the links on that page seem to point to a different zine ("Red flags: Before you join that org") than one about Flock. I tried a few likely URL substitutions but couldn't find the intended PDF.

EDIT: Just clicked the publisher username and found it has correct links: https://unsalted.noblogs.org/post/2025/03/27/new-zine-birds-of-a-feather-destroy-a-flock-together/
