A troll is Internet slang for a person who intentionally tries to instigate conflict, hostility, or arguments in an online social community. Platforms targeted by trolls can include the comment sections of YouTube, forums, or chat rooms.
Trolls often use inflammatory messages to provoke emotional responses out of people, disrupting otherwise civil discussion. Trolling can occur anywhere that has an open area where people can freely post their thoughts and opinions.
Another way to spot a troll is by their persistence. When trolls sense that they’re getting an emotional response out of someone, they usually won’t stop until they’ve gotten their victim sufficiently riled up.
Trolls are also known for their outlandish and outrageous claims. They will often make ridiculous statements about the subject at hand, again with the expectation that they will get an emotional response out of people. Trolls won’t necessarily believe the outrageous claims they make, but their goal is to convince you that they do believe it.
