What is a doxxing truck?

Excuse me, could you please clarify what you mean by "doxxing truck"? Is it a specific type of cyberattack or a term related to the practice of exposing personal information online, commonly known as doxxing? If it's the latter, I'm not familiar with the term "doxxing truck" being used in the context of cryptocurrency or finance. Could you provide more context or explain further what you're referring to? It's possible that this term is being used in a specific community or forum that I'm not aware of.
