Kissner, Twitter’s former chief information security officer, or CISO, resigned from the company on Thursday. Kissner, who uses they/them pronouns, announced their departure on Twitter, but did not specify a reason.

“I’ve made the hard decision to leave Twitter. I’ve had the opportunity to work with amazing people and I’m so proud of the privacy, security, and IT teams and the work we’ve done,” they tweeted.

They were Twitter’s most senior cybersecurity official, and their departure and others have raised eyebrows over at the Federal Trade Commission. The company is under two FTC consent decrees for violating user security and privacy in the past. Violating the decrees risks generating billions in fines from the federal agency.

Yoel Roth, who has been reassuring users that Twitter was still moderating hateful conduct and misinformation, left the company on Thursday, Reuters reported. Roth was Twitter’s head of trust and safety.

According to Platformer, the tech newsletter helmed by Casey Newton, Roth was a Twitter veteran who had been at the company for seven years. On his LinkedIn profile, Roth explained that he was in charge of Twitter’s policy and threat investigation teams tasked with dealing with security, authenticity, and content issues. Since Musk’s takeover, Roth had been largely seen as the calm voice reassuring users (and advertisers) that it was still taking content moderation seriously.

Roth did not make any public announcement about his departure. However, his Twitter profile describes him as “Former Head of Trust & Safety at Twitter.”
