I am not a lawyer, this is not legal advice, etc. Assuming you mean the Mexican constitution, it's kind of vague: Article 6 . The expression of ideas shall not be subject to any judicial or administrative investigation, unless it offends good morals, infringes the rights of others, incites to crime, or disturbs the public order. "Offends good morals" is not defined anywhere, so it's up to interpretation whether that includes fraud. "Infringes the rights of others" is defined in various places, but in similarly vague terms.
