AI topic detection, quality signals, and rate limits

A layered moderation system: AI topic detection flags off-topic posts, quality signals rate depth, duplicate grouping, and rate limits prevent spam.

What it does

Built for the way research actually happens

The Lounge is moderated by a layered system that keeps signal high without manual overhead. An AI topic detector classifies every post the moment it is submitted — off-topic posts in a community are flagged for moderator review. The detector never deletes content; it only surfaces signals.

Quality signals rate the depth and originality of each post and feed back into feed ranking — high-quality posts reach more readers, low-quality posts stay in their community. Duplicate and near-duplicate posts are grouped so the reader sees one canonical version. Rate limits prevent spam without blocking legitimate engagement.

How it works

Three steps from idea to outcome

1

Post is submitted

The AI topic detector classifies it instantly and the quality signal is computed.

2

Signals are surfaced

Off-topic posts are flagged for moderator review. Duplicates are grouped.

3

Moderator decides

A human moderator reviews flagged posts. Nothing is removed automatically.

Why it matters

Benefits that compound

  • AI topic detection flags off-topic posts for review
  • Quality signals rate depth and originality
  • Duplicate and near-duplicate posts are grouped
  • Rate limits prevent spam without blocking real engagement
