Lisa Jennings Young, Twitter's former head of content design, was one of the people who specialised in introducing features designed to protect users from hate. Twitter was a hotbed for trolling long before Mr Musk took over, but she says her team had made good headway at limiting this. Internal Twitter research, seen by the BBC, appears to back this up.

"It was not at all perfect. But we were trying, and we were making things better all the time," she says. It is the first time she's publicly spoken of her experience since she left after Mr Musk's takeover.

Ms Jennings Young's team worked on several new features including safety mode, which can automatically block abusive accounts. They also designed labels applied to misleading tweets, and something called the "harmful reply nudge". The "nudge" alerts users before they send a tweet in which AI technology has detected trigger words or harmful language.

Twitter's own research, seen by the BBC, appears to show the "nudge" and other safety tools being effective.

"Content design"

"...because tech platforms are perhaps the most important speech regulators in the world." 

Two simple and obvious points: 

Social media companies make their money by creating mobs; liberals want to censor the mob and leave the instigator untouched.

In France, and Twitter, you can mock Muslims and and Turks but not Jews or trannies.

A prominent advocate for women’s rights in France is being taken to criminal court over accusations of “misgendering” two transgender public figures. Dora Moutot, a best-selling author and social media influencer, is facing a legal complaint alleging insults on the basis of gender identity, and public incitement to hatred or violence towards a group of people on the basis of their gender identity.
