For 17 years working in trust and safety, I've watched talented people burn out on impossible tasks. The problem isn't the people, it's the systems. Traditional moderation requires months of retraining for every policy change. Only big companies can afford it, and even then it works poorly. 🧵 1/9

All of my group chats are responding to Homan’s announcement by asking everyone to double down because:
1. ICE is still out there and abducting people today. We can’t trust the occupation is over until we actually see it.
2. People are going to be in an economic crisis for a very long time.

I do not wish to be mean, but if I hear you in the year 2026 claiming that Elon Musk "saved free speech" from "leftist censors" I am going to question your judgment on pretty much everything else, because you do not live in reality.

Minneapolis should press its momentum and demand not only withdrawal but start talking about the need for immediate reparations, loudly, with the total certainty that only winners have. "You have wronged us terribly and must pay recompense" and let them argue the second part.

@techpolicypress.bsky.social was kind enough to host my reflections on just how far we’ve already come with AI-assisted content moderation.
We’ve got a long way to go, but the difficulties that used to serve as (legitimate) excuses are fading fast.

Scrolling through the photos of Pam Bondi's "Minnesota rioters," it's just hero after hero. Every photo includes a cowardly DHS agent with their back to the camera.
Bondi thinks she's going to win the propaganda war with this shit, but it's never been more clear that they're losing.

Guys maybe the number one obstacle to organizing here in Minneapolis is the unfounded fear that if you get involved, DHS will put you on a list and assassinate you. It leads people to avoid organizing or act in ways that are completely detrimental to organizing. Please please do not spread that fear

A lot of the time, specific people and organizations are the problem, and an unwillingness to say that clearly is, itself, a part of that problem.
I truly, truly get it why a lot of good people are saying that Minneapolis is not about left or right, democrats or republican, now. I understand. But I’m sorry it actually is

Please reshare the below post, unfortunately some accounts with lots of followers have reposted the false claim and loads of people are falling for it.
I'm seeing people mistakenly claim the gun photo was posted before today, but its just how Google sometimes dates images based on the original date of the thread its posted in, not when it was posted. The photo was posted an hour ago in this 5 day old thread

By who? Who shot the person dead? You saw the video. We all know a federal agent shot a man dead who was prone on the ground. Also, it's not "according to officials." It's according to verified video seen with your eyes. Not saying what anyone can obviously see with their eyes is a form of lying.
