Mexico’s financial consumer protection agency, CONDUSEF, sets rules for debt collection agencies. They may not use “listas negras, cartelones, o anuncios, que hagan del conocimiento del público la negativa de pago de los Deudores” (blacklists, posters or notices that make known to the public that debtors have not paid). They may not threaten, offend or intimidate the debtor’s relatives or coworkers.
In December 2025, El Imparcial reported CONDUSEF’s position that exposing debtors on social media or posters is “no solo es inapropiado, sino ilegal” (not only inappropriate, but illegal). Such practices “vulneran la privacidad y la dignidad de las personas” (violate the privacy and dignity of people).
