Cyber/Internet Troll
A Cyber/Internet troll is a person who deliberately sows discord on the Internet by starting
quarrels or upsetting people, by posting inflammatory or off topic messages in an online
community, just for amusement. Since trolls thrive on attention, the best way to discourage
trolls is not to pay any attention to their comments.

Cyber Bullying
Any insulting, degrading or intimidating online behaviour like repeated posting of rumours,
giving threats online, posting the victim’s personal information, sexual harassment or
comments aimed to publicly ridicule a victim is termed as cyber bullying.
It implies repeatedly targeting someone with intentions to hurt or embarrass. Bullying online
can have very serious implications on the other person (victim).

Cyber Stalking
This is a kind of online harassment wherein the victim can be subjected to a barrage of online
messages and emails. These stalkers know their victims and instead of resorting to offline
stalking, they use the Internet to stalk.
A cyber stalker relies upon the anonymity afforded by the Internet to allow them to stalk their
victim without being detected.
