Mark Cuban may not be running for president in 2016, but the billionaire entrepreneur has a few ideas about the future of privacy and America's election etiquette.

In a blog post Sunday, the Dallas Mavericks owner detailed what he thinks is the most dangerous question that can be asked of a candidate.

"I can't think of anything worse I want to hear coming from someone that holds a public office or is a current presidential candidate than 'What do you have to hide'?" Cuban wrote. "The question is extremely dangerous when coming from a public official or someone running for an office.

"It is being asked for no other reasons than to intimidate and to throw the subject's privacy out the door and open them up to public scrutiny."
