El Blog del Narco has faced relentless legal and ethical scrutiny. Mexican authorities, including attorneys general and lawmakers, have condemned the channel for allegedly violating laws against the dissemination of violent content. In 2021, a lawsuit was filed against the blog by a man whose brother was featured in a video; plaintiffs argued the footage caused psychological distress and dehumanized victims. The channel has also been accused of trafficking images for profit, with critics pointing to their monetization of violent content via YouTube ads.
