The full terms are on the Terms page. In practice it comes down to this:
- Be honest about your work. Do not claim someone else's project, answer or achievement.
- Be decent. Disagree with the idea, not the person.
- Do not spam. No mass DMs, no affiliate links, no engagement rings.
- Do not cheat the numbers. Alternate accounts, traded likes and faked proof all get the XP taken back.
- Do not post other people's private information.
Consequences run from content removed, to XP and badges taken back, to invites revoked, to the account removed. Serious cases skip the earlier steps.
