A person who posts derogatory messages online targeting people is called a cyber troller.
Answer
True
Reason — A cyber troll is a person who starts quarrels or upsets people on the internet by posting inflammatory, digressive, extraneous or off-topic messages to an online community with the intent of provoking readers into displaying emotional responses and normalizing tangential discussion, either for the troll's amusement or for a specific gain.
