Stack Overflow paid moderators in points, not money

Stack Overflow, created in 2008 as a question-and-answer site for programmers, accumulated 3.5 million questions and 6.9 million answers from 1.3 million users in its first four years. Its norms are famously strict — only well-documented, on-topic, correctly tagged posts survive — and enforcing that at such volume with employees would have been impossible.

The site instead made contribution itself the currency of governance: peer votes award reputation points, and reputation unlocks moderation privileges. The ladder is explicit and measured in the research literature — up-voting at 15 points, down-voting at 125, viewing and casting close votes at 250, access to review queues at 500 — with progressively smaller fractions of users holding each higher power.

Every act of quality control is performed by users who earned the right to perform it through prior contribution. The research on the site's first years found high-reputation users are the primary source of answers and especially of high-quality ones — meaning the people who hold police powers are the proven contributors. Flags, edits, review queues and close votes run the site day to day, with a small elected layer above them for binding decisions.

Paid moderators in power, not money: contribution-earned reputation unlocks governance tools, so enforcement scales with the community and moderators are proven experts.

Voting simultaneously ranks content and grades the author, so curation and reputation are one act.

Privileges earned only through contribution ensure moderators have context and their reputation is collateral.

Thresholds create a pyramid where responsibility grows only as fast as demonstrated behavior.

Recognition and influence are exactly what expert users seek, so the reward cannot be outbid.

Let contribution earn governance power: your best users become your police, and the wage costs nothing.

Community moderation scaled to 3.5M questions and 6.9M answers from 1.3M users (2008-12) — by voting and earned privileges, not staff The reputation-privileges ladder became the default governance template for user communities — forums, wikis, open-source trackers — and Stack Overflow became the canonical research setting for studying community self-governance.
