I’m wary of “countercultural” sites run by a “small crew” not identified soliciting emails with no privacy policy in place. If it isn’t a honeypot it’s indistinguishable from one. Assuming it isn’t, the email list itself is ambiguous regarding GDPR compliance. It seems counter-intuitive to me that the intended audience would sign up for such an email list under such a cloud of uncertainty. With anonymity comes avoidance of accountability. Why would I visit such a site if I have nothing to gain and so much to lose from interacting with a site whose operators have inscrutable and seemingly paradoxical intentions?

I’ll ask more directly since I was vague before. Are you associated with thoughtmaybe.com? I only ask because you seem to be advocating for using it under the guise of a user or fan of the site, and not as operator or staff of the site; to not identify yourself as staff when commenting on the site could be interpreted as commenting in bad faith. If not then please disregard this paragraph.
