Gruff

It was inevitable that with the tide gradually turning against bullying, including cyberbullying, that trolls would find themselves on the receiving end of unwanted attention too. There's a piece in today's SMH in which a troll positively gushes with self-contradictory excuses: she's a performance artist, she's only joking, she's an activist, it's harmless fun, get a sense of humour, it's your own fault, you deserved it. As important as it is to always take any quotes in a newspaper article with a few grains of salt, there's a hint that she has damaged her relationship with her circle of friends, too, and simply doesn't realise it. If so, that would fit with the profile of a bully as someone with poor social skills who doesn't realise how unpopular they actually are.

(A transcript from current affairs program Insight, from which IIUC the quotes are taken, will be available later. ETA: None of the quotes from the SMH article appear in the transcript, so I'm unclear as to their source.)
