### Explanation Subscription publications are author- or organisation-driven channels where readers opt in to receive a periodic, long-form output — the platform handles distribution and the back-catalogue, the author handles the writing. The category covers modern newsletter platforms (Substack, Beehiiv, Ghost, Buttondown, creator-run Mailchimp campaigns), email-distribution lists used by technical communities (Linux Kernel Mailing List, Debian and Fedora dev lists, oss-security, full-disclosure, IETF working groups), RSS-friendly blogs maintained as personal publications, and increasingly Telegram and WhatsApp channels that function as one-way newsletters without using email at all. For OSINT, subscription publications concentrate a target's most thought-through public output in one place. Every issue is usually publicly indexable; comment threads (where enabled) surface a like-minded audience and recurring real-name commenters; cross-posts on the author's other channels link the publication identity back to a social-media identity. Stylometry against a multi-year archive tends to give a strong signal because the text volume is large and intentional. Technical mailing lists carry an additional pivot: the author's real working email is usually exposed in the `From` header, which often differs from any handle they use on social media. ### Examples {{some links to articles, videos, etc}} ### Types business, behavioural ### See also - {{internal links to similar functionalities}} ### Typical weaknesses - {{internal links to typical weaknesses}}
