For your request
Not mine, but on behalf of the list, on behalf of all who have complained about these spammers and personal abusers over the years. Users obviously don't have ability or desire to filter such spam and abuse, so your ideals don't reflect the reality of what global users expect of lists. And your inaction to remove such spammers and abusive posters has, along with them, destroyed this list over the years, evidence in point: everyone and all convo has left, with many filing written complaint. Society does not succeed when left to savages. So now you're left with a grand freepost list that no one but spammers post to. The cumulative complaints from people were not so much about freespeech topic, which lists tend to self steer and correct on a social basis, but about the spammers and abusers intentionally and egregiously spamming and abusing people and refusing all requests to quit their wanton malbehaviour. In the end, you yielded exactly what you supported and refused to fix. And you also blocked access to the archives so that no one can read or download or link them without first swearing allegiance to Cloudflare over the clearnet. Ye who fails to heed the wisdom of the Internet's long held rules on spam and abuse, ends up with an abandoned service. Amazing that no one has forked and rebooted the list, yet again.

Which was apparently due in the first place to, you guessed it... these spammers spamming. Thus that's an invalid argument...
Many gmail users have been automatically unsubscribed
And let us just admit that the vast majority of such non-posting accounts are, shall we say, not in support of the cypherpunk movement.

Invalid, the spammers still continue to spam and abuse, at effectively zero cost to them, all win, no downside. Spam and abuse are still spam and abuse. The Internet decided that issue 35+ years ago, and provided real options to deal with it. Pick one.
