RedNote is seeing the largest influx of new users right now. There's a few other TikTok-like apps that are also seeing some bumps, but RedNote is soaring.
By and large, the average user is a content consumer, not a creator. The consumers want to go where the creators are, but the creators won't go where there aren't already consumers. This will always be the biggest problem for any Fediverse platform.
It's pretty standard when a highly-publicized murder suspect's online profiles are discovered. Platform admins will typically disable/hide their accounts from the public while investigations/trials are ongoing. This is hardly unique to Luigi.

The queer black mom AI is the one I keep seeing right-wing commentators putting on their thumbnails for their videos/articles. They're putting more focus on the character rather than the tech, from what I've been seeing.
People are taking issue with the fact that the AI was black and queer, not that it wasn't a real person in the first place. Once again, the right is angry at something that literally does not exist in real life.
