These ten “personas non grata” are people you probably don’t want in your product or service, but who are likely to find their way in anyway.

If you’re on mobile, the Personas Non Grata mobile app includes news stories that show what these characters have been up to lately.

Why no “hacker”? Because any of these personas non grata can use a digital attack.

Why no “troll”? Because we don’t care whether they are being “funny” or not, and that’s not the conversation we want to have.

Why no “racist” or “homophobe” or “misogynist”? The personas below cover actions, not motivations. Any of these may be motivated by racism, misogyny, homophobia, etc. That’s an important discussion, but a different one.
