Derailing (or derailment) refers to the deliberate behavior of derailing a discussion or debate. It is a form of provocation in which a person intentionally sabotages topics or conversations to draw attention to themselves and disrupt a factual or reasonable discussion.

In the context of social media and influencer marketing, derailing (also known as trolling) refers to users who deliberately derail a debate through provocative comments or actions in order to create chaos or provoke a reaction. The goal is to steer or block the discussion rather than contribute constructively.
