Factual Their own work or organisation

Astral Codex Ten has an unofficial subreddit, Discord and bulletin board, and in-person meetups around the world.

Unresolvable The public record could not settle it.

Factual: Statements about the present or the past, checked against the record: did they hold up?

What would count as true or false

There are four parts: an unofficial subreddit, a Discord, a bulletin board, and in-person meetups around the world. True: around October 2026, all four exist and are active, and meetups take place in several countries. Mostly true: all four exist, but one detail is slightly off (for example, one community is official rather than unofficial, or meetups are spread less widely than 'around the world'). Mixed: about two or three of the four hold. Mostly false: only one holds. False: none of them exist.

Reasoning

The ACX meetups listing for 2026 says meetups were planned in over 180 cities, from Aachen, Germany to Zagreb, Croatia (E1/E5). An independent Meetup.com event page separately confirms the twice-yearly community meetups (E3), so the meetups part holds. The only Discord evidence is two Discord invite links in the meetup listing (E4, E6), which do not by themselves show an ACX-wide Discord. No evidence speaks to an unofficial subreddit or a bulletin board, so the evidence cannot tell whether one, two, three or all four parts hold, and the verdict cannot be settled under the criteria.
