"Naming-and-Shaming: We do not allow posts or threads that are created for the purpose of “naming-and-shaming” other community member(s). “Naming-and-shaming” is the act of creating a post to call out an individual or group by name, and making them the subject of public accusation, ridicule and/or shaming. Generally, naming-and-shaming involves an in-game situation and/or Terms of Service violation, which the ESO Community Team is unable to assist with. A certain amount of rivalry and competitive razzing is healthy for any game community, especially one with PVP elements, but naming-and-shaming goes well beyond that. It typically elevates to a point where the subject feels legitimately harassed. We believe that naming-and-shaming posts and threads can be abused and are very harmful to the community. We also don't feel that publicly calling out or accusing others by name on our forums is in spirit of the game or our community. If you genuinely believe someone has violated our Terms of Service, you should report them in-game via the support interface — do not bring the situation onto the official ESO community forums."
