But how is that a different problem than mastodon or Lemmy or friendica face? What makes TikTok different?

I mean network effects are real. You always have a hard time moving users over to a new network platform. Are you saying that anyone using TikTok right now arguable does not care about privacy at all so would be unlikely to see the value of federated decentralized apps?

But what all is needed for tracking? AI-based metadata extraction from the video and metrics of how long the user watched the video before swiping or rewinding or stuff? That can all be done at the instance level. I’d imagine the bigger issues is the engineering involved in the app content creation tools, and the costs of data storage for all of those videos and bandwidth for distributing them, something TikTok currently just foots the bills for. Arguably an open source equivalent wouldn’t have the privacy stigma around it, right?

Delete the login and re enter it. That worked for me

Arguably if you are worried about remote admins, that’s not a problem-you just issue the creation of the Note without an owning user or pointing to a magical AnonymousCoward user and change the server code to allow that. Then when the note propagates across instances nothing links it to the original user. Of course the downside is the original user won’t get notified of replies to the post and such, but so much is the price of anonymity, I guess

But an evil instance admin would also be able to log the IP of the throwaway account too. So that’s not any better. The bigger issue is with the moderation side - how do admins deal with troll anonymous posters? Blocking an account is less useful when there’s no account. Arguably it could be a community-specific option to allow anonymous posting.

Yes. This is my new Reddit replacement

Actually, a scriptable filter (JavaScript? Lua?) for individuals might be nice in a client app or web app

I’m already considering self hosting my own instance, so I’m probably not your target demographic, but I would leave pretty quickly from an advertising instance. If an instance wanted alternative funding they could offer plans with value add of some other type if they wanted to subsidize server costs
