Australia’s internet safety watchdog on Thursday threatened to fine Twitter for failing to tackle online abuse, saying Elon Musk’s takeover had coincided with a spike in “toxicity and hate”.

E-safety commissioner Julie Inman Grant – a former Twitter employee – said the platform was now responsible for one-in-three complaints about online hate speech reported in Australia.

Inman Grant said Twitter had 28 days to show it was serious about tackling the problem or face fines of Aus $700,000 (US$475,000) for every day it missed the deadline.
