Ever wondered how Incels and RWEs gatekeep new members online? We did! We find two fundamentally different ways in which members socialize in these extremist communities. Intriguing work by @cvdavid.bsky.social!

The Disastrous Rollout of the Trump-Approved TikTok Serves as a Stark Warning for Us All Big Tech platforms wield far too much power over our information landscape to continue operating without transparency.

I know there is a vivid debate around how to operationalize hate speech. Not sure I agree with TT-US' understanding of what constitutes hateful content:

X wants to call you out for using a VPN (and maybe catch a few trolls, too) The situation began in October when Mikita Bier, X's Head of Product, announced that new information would be shown on user profiles, such as the date they...

What is the gossip on why X is releasing new content moderation features? Seems off-brand to me. What am I missing?

@riekers.bsky.social is doing awesome work using multi-agent systems, in this case to detect hate speech in memes. Quite a challenging task but a promising approach and much more to come.

Reach out if you're interested or struggling to find explainable AI solutions for multimodal applications

Published 2025 but maybe already outdated? The rapid advance of AI and the fundamental shifts to our (increasingly hyperpersonalized) information environment, we might have to revisit this sooner than expected.
