Publishing Guidelines
Read and agree to the individual community rules before posting, since they sit on top of the sitewide guidelines and are enforced by that community moderators. Post on topic and expect posts to be contained within the community rather than reaching the wider dashboard.
💳 Free Plan Details
Free for any Tumblr account. Communities are topic spaces with their own feed, moderators and rules, separate from the main dashboard. Posts can be reblogged into a community but not back out of it. Replies work like a conventional comment section.
👍 Best For
Interest-based discussion, fandom and hobby communities, reaching a focused audience away from the main dashboard algorithm, community building around a niche.
👎 Not Good For
Content violating the Tumblr Community Guidelines - harassment, hate speech, violent content, non-consensual or underage sexual content, spam, malware and deceptive links - plus whatever additional rules each community sets. A weak fit for broad reach or link building: content is contained within the community, cannot be reblogged outward, and non-members see only the post feed and About page.
⚠️ Common Blocking & Rejection Reasons
Breaking a specific community own rules, harassment or hate speech, spam, deceptive links or malware, sexual content involving minors or non-consensual imagery, reaching the report threshold that auto-hides a post.
🛡
Moderation Notes
Two-layer moderation: sitewide Tumblr guidelines plus per-community admins and moderators. When a post or comment hits a report threshold set by the admins it is automatically hidden and queued for moderator review.

SEO & Public Visibility
Limited. Public communities can be viewed by non-members including logged-out visitors, but only the post feed and About page are exposed - member lists, reactions and comments are hidden. Content cannot be reblogged out of a community, so reach stays contained. Treat as community building, not an SEO or distribution channel.
