What is "trolling," and how has it evolved on the internet?

Trolling is the act of deliberately provoking or upsetting people online by posting inflammatory, off-topic, or disruptive messages. Originally, trolling was seen as a form of online pranking or mischief, often done for humor or to spark debate. However, it has evolved into more malicious behavior, where trolls target individuals or communities to cause emotional distress or spread misinformation. The anonymity of the internet allows trolls to act without facing real-world consequences, contributing to the toxicity in online spaces and making it challenging to maintain constructive discourse.
