The Case of the Vanishing Vector
- Decide scope (which boards and time span).
- Use 4chan’s JSON API to poll boards at a frequency sufficient to capture thread creation (real-time or frequent short-interval polling).
- Save both post JSON and media files; generate checksums.
- Link rot and media deletion
- Archive takedown due to legal complaints
- Storage decay and format obsolescence
Competitors: Smaller or board-specific alternatives include 4chansearch, 4chanarchives, and Randomarchive.
Public Web Archives: Sites like Warosu and Desuarchive provide searchable databases of specific boards, such as /lit/ (Literature), /tg/ (Traditional Games), and /pol/ (Politically Incorrect).
