¿Por qué ocurre constantemente este error en mi foro? ¿Es seguro ignorarlo?
Excepción de trabajo: PG::UniqueViolation: ERROR: el valor de clave duplicada viola la restricción única "index_users_on_username"
DETALLE: La clave (username)=(ghazal1) ya existe.
Se necesita mucho más contexto: ¿cuál es el backtrace y qué hay en el entorno?

No sé si está relacionado o no. Registro usuarios mediante la API. Obtengo el nombre de usuario del usuario y verifico si existe con la API; si es así, elijo lo que Discourse sugiere. Sin embargo, muchas veces lo que se sugiere es en realidad un nombre de usuario real de un usuario que de alguna manera está roto. Es decir, cuando intento ver su perfil, obtengo una página de error de no encontrado.
Por cierto, reporté estos usuarios rotos aquí:
