Can you promote here?
Promotion is allowed only with moderator permission (or inside designated threads). A short, honest modmail before posting costs two minutes and functions as a safe-conduct pass; skipping it is the most common avoidable removal.
From the rules · Companies must get prior mod approval for ads/sales/giveaways; use r/DHExchange for requests; Free Post Friday requires [Free-Post Friday!] flair.
Links
No explicit link policy. Default to no URL: link-plus-young-account is one of the most common automated removal patterns on Reddit.
What this community rewards
Dominant post formats: news, guide, showcase
Headline: short, descriptive (e.g. “224TB Unraid build — parts, costs, lessons”). First‑person is fine for project writeups; neutral for news. Typical length: medium→long with technical detail, logs, steps, and provenance. Tone: factual, archival-minded, helpful. Upvoted: original archives, deep tests, preservation news, detailed how‑tos; Removed: memes, low‑effort purchase pics, requests or unapproved ads.
Arriving in the local format matters: cross-posting the same text everywhere reads as tourist instantly. The wider method is in the Reddit playbook.
Classified mechanically from the community's published rules and recent top posts, last checked August 2026. Rules change and moderators have the final say: verify at r/datahoarder's rules page before posting anything that matters.
Thread Otter checks this before every send
These profiles power the product: promo-banned communities never receive a promotional draft, drafts arrive in the local format, and a fact-check gate plus human pacing protect the account doing the talking.
