# Vendor facets — Reddit, a subreddit as a developer community. support_channel (2 pts) is the
# only check it touches, and the half credit it gets today exists only because Community pointers
# are never probed: www.reddit.com serves the same 8.4 KB page for a real and an invented
# subreddit, so a probed pointer grades soft-404 and earns zero.

summary: >-
  A subreddit is the weakest community pointer on the Kin Score. Declared as Community it earns half of
  support_channel (1 of 2 points) only because that type is never probed. Declared as Support it is probed,
  and www.reddit.com answers every subreddit path, real or invented, with the same 8.4 KB page (checked
  2026-09-25 with both a browser and a bot user agent), so it grades soft-404 and earns nothing, as the
  one Reddit support pointer in the catalog already does. Subreddits are also created and moderated by
  redditors, so a provider may not own the community it points at.

    Only while Community pointers stay unprobed. Declared as Support, or once the probe reads Community,
    www.reddit.com returns an identical ~8.4 KB 200 for a real and a nonexistent subreddit, the pointer
    grades soft-404 and the credit is 0. The one Reddit support pointer in the 2026-09-22 probe (r/OpenPoker)
    already grades soft-404.
  provider_must: >-
    Declare the subreddit in apis.yml common[] as Community; declaring it as Support gets it probed and
    zeroed.

    A subreddit hosts no provider document a pointer check could read, and reddit.com's catch-all response
    defeats the liveness probe for any of them.

  A model, not a score. Adopting this vendor changes a provider's Kin Score only when the provider publishes
  the resulting artifacts on its own surface; nothing here writes a score, and no sponsorship or partnership
  can.
