Tor Forum Hosting — Private .onion Discussion Communities

We support multiple forum platforms optimized for .onion hosting. Discourse provides modern, real-time discussion with rich formatting, categories, and a responsive interface. phpBB and MyBB offer traditional forum layouts with proven stability and extensive customization. Flarum delivers a clean, fast experience with a modular extension system.

Each forum platform is configured specifically for Tor operation. We disable external resource loading, configure avatars to use local Gravatar alternatives, route email notifications through Tor, and optimize database queries for the concurrent read-heavy workload that active forums generate. Rate limiting prevents automated spam registration without blocking legitimate Tor users.

For maximum privacy, we also support custom forum software built on top of frameworks like Django or Node.js. Purpose-built forum software can implement privacy features that off-the-shelf solutions lack, such as automatic message expiration, deniable messaging, and onion-routed private messages between forum members.

Forums on Tor can support varying degrees of anonymity depending on your community's needs. At one extreme, fully anonymous forums allow posting without any account at all — users are identified only by random session tokens that expire after a configurable period. At the other extreme, pseudonymous accounts with invite-only registration provide a persistent identity without requiring real-world information.

Our forum hosting supports anonymous authentication tokens that let users maintain a consistent pseudonym across sessions without providing an email address or password. Authentication uses Ed25519 key pairs generated in the browser — the user's private key never leaves their device, and the server stores only the public key. Account recovery uses a recovery phrase rather than email.

For forums that require email for notifications, we integrate with .onion email servers (including our own email hosting) so that the entire communication chain stays within the Tor network. Alternatively, forums can use Tor-accessible push notifications or RSS feeds to alert members of new posts without requiring any email address at all.

Moderating anonymous forums presents unique challenges. Traditional moderation tools rely on IP banning and account suspension, but Tor users can easily change circuits and create new accounts. Our forum hosting includes advanced moderation tools designed for this environment: proof-of-work registration challenges, content-based spam filtering, behavior analysis, and configurable posting rate limits.

We deploy a machine learning-based content filter that identifies spam and abusive content based on linguistic patterns rather than user identity. This filter is trained on forum-specific data and runs entirely on your server — no content is sent to external services for analysis. False positive rates are low, and flagged content goes to a moderation queue rather than being automatically deleted.

Moderator actions are logged with cryptographic accountability. Every moderation decision — post removal, user suspension, rule change — is recorded in a tamper-evident log that community members can audit. This transparency builds trust in moderation decisions and prevents moderators from abusing their power without community oversight.

Active forums generate significant database load as users browse threads, post replies, receive notifications, and search content. Our forum hosting is configured with database optimization as a priority: PostgreSQL with tuned connection pooling, materialized views for frequently accessed forum statistics, and full-text search indexes that deliver instant results.

Caching plays a critical role in forum performance on Tor. We configure Redis-based caching for rendered posts, user profiles, category listings, and permission checks. With effective caching, the vast majority of page views are served from memory without hitting the database, reducing response times from hundreds of milliseconds to single digits.

For large forums with thousands of active members, we offer multi-server deployments where the web application, database, search engine, and background workers run on separate servers. This horizontal scaling approach lets each component scale independently. The web tier handles connection concurrency, the database tier handles query volume, and the search tier handles full-text queries — all behind your single .onion address.
