What is trolling?

The term trolling stems from the internet slang ‘troll’, which is a person who starts arguments or upsets people by posting inflammatory, extraneous messages online.

The aim of a troll is to provoke other online users into an emotional response often for their own amusement. Trolling is the associated verb to ‘troll’ and was originally thought to be the same as ‘flaming’ – defined as a a hostile interaction between online users which often involved insults and profanity. However, the term troll has changed to refer to any content that targets another person.

Isn’t trolling just cyberbullying?
