Rules for every card
- The source is named in plain text on the card and in its ⋯ sheet, with the source's publication time and, in the sheet, the card's published and updated dates.
- Every card links to the original. A card without a credit line or link cannot be published.
- No agency logos, seals or insignia are used.
- No "official", "approved by" or "in partnership with" wording about any source.
- No images from sources are shown.
- Weather cards say they are not official warnings and point to weather.gov; they leave the feed when the alert ends.
- No other outside source is used. Third-party material (news-agency copy, partner articles, company announcements, images) is excluded rather than credited.
