Those spam messages aren't going through the list server. They just use
subject lines from list messages, and reply by Message-ID. For example,
one of my recent posts to tor-talk:

Message-ID: <382f20c5-fe74-49d4-0f0f-1e5a35fd8d98 at riseup.net>

And the triggered spam:

Message-ID: <664f41dc19a32065d9acce123812367c at app09.jetlumen.com>
In-Reply-To: <382f20c5-fe74-49d4-0f0f-1e5a35fd8d98 at riseup.net>

And the pre-Riseup routing headers:

Received: from m41.bytekeys.com (m41.bytekeys.com [107.189.161.196])

No header contains "*.torproject.org".
