I built a little hybrid bookmarking/notetaking app - https://www.showboard.ca/ It's not built for bulk usage like you're describing, but makes it easy enough to scrape, modify, share and search. Let me know if this is of interest (it has a python backend ;)

Do you have an ActivityPub interface to follow shared posts?

No, the sharing aspect is internal to the app, so each "board" can have as many users as you like. Neat idea though, I'll have to look into that.
