What is the most professional way to publicly shame a client who refuses to pay a large invoice?

[Btaliat]

Imagine you are working for a big client that have already agreed to pay you, but later reneged the promise without even thinking about the efforts and the stress that you gone through, including the money. You know you will not want to cause drama by publicly shaming the person on the social media because you will not want your name and reputation to be soiled as well. What will you think about this?
