Every community sets its own rules on top of these site-wide ones.

Remember the human

Disagree with ideas, never attack people. No harassment, hate or threats.

Vote on content, not people

Upvote what adds to the conversation, downvote what does not. Do not ask for votes or use extra accounts.

No spam

Post where it fits, credit your sources and do not flood communities with self-promotion.

Protect privacy

Never share someone’s private details.

Report, do not reply

Use the Report button. Community moderators and site moderators review reports and may remove content or ban accounts.
