No Internet Archive copy: we ask it for a few hundred fresh posts a day, from the accounts that delete the most. X's data for every post is in the WARC records above.

How to check:
1. Download a file above and run: shasum -a 256 <file>. It must print the SHA-256 shown, and that hash must appear in the list.
2. Drop the list and its .ots file on https://opentimestamps.org, or run: ots verify <list>.ots
   That proves the list, and every file whose hash it holds, existed unchanged by then. Fresh timestamps reach Bitcoin within hours.
