One network, a few rules, and a promise that they are enforced.
• Photographs you made. • Places you are willing to send a stranger. • Captions that tell someone something useful about the light.
• Anyone else's work. • Hateful, harassing, sexual, violent or illegal content. • Anything targeting a particular person. • Coordinates of a home, a nest site, or anywhere that a crowd would ruin. • Advertising, links, or spam.
Use Report in the menu on the photograph, the comment or the profile. Reports are read within 24 hours and content that breaches the guidelines is removed, with the account suspended or terminated for anything serious.
Use Block on a profile to stop seeing somebody at once, without waiting for anyone. They are not told, and it takes effect immediately.
You are told what was decided and why, under Profile → Account → Moderation, and you can object once. A person reads the objection and decides again.
