@lety Thank you for the support. My next step would have been to explore the fedi.buzz API and the possibilities of combining several public Fediverse APIs. Emelia Smith, who has worked on moderation and trust & safety tools for the Fediverse, kindly helped me improve auto-deletion and similar features, so I thought it was okay to do something like this. But I guess not. It seems that public posts cannot be used publicly in any way, according to the Fediverse Police / HOA forces. Still after this time I'm a bit sad about everything that happened.
