Yes! There would be a spec written for blocklists that could be applied to Lemmy or PoeFed. You can quickly toggle on/off a blocklist. For example, I can subscribe to a “US Politics” blocklist, and toggle it on/off when I need a break from news.
Is it only an idea? I can think of automatic tagging of all posts. If you have access to a post and all its comments, probably you can programmatically assign a tag to it. Based on “words cloud” or something like that. Annoying posts usually have a lot of comments which simplifies automatic tagging. It can make it possible to filter out specific topics, or, contrary, browse them specifically.
But where do you store the computed tag? I guess you could hack it by having a bot that comments the computed post tags on the post itself, but that's messy.
If computing these tags is not expensive, they can be computed and stored internally in the app at client side. If this will work and will be useful, it can be moved to server-side in one of lemmy’s updates. Each post will have have probable tags in metadata with % of how sure an algorithm was about assigning this tag. Personally, I think affecting your feed by picking appropriate instance doesn’t work, and I do hope other instance-independent ways to browse lemmy will become available. But right now I haven’t found a time even to check Lemmy’s api to see what’s already available.
I don't think this will work within the context of a feed of posts. You would have to make at least 1 additional comment for every post in the feed to fetch the comments for a post. So if you fetch a feed of 50 posts, you will have to make 51 requests. If a post has too many comments to fetch in one page, you will have to iterate through all the pages until you have all the comments. So it's actually >=51 requests. Though I suspect you could get a good idea of a posts comments by fetching just the first page of comments.
PieFed seems to have tags, but I'm not exactly sure how they work. But that might be a better place to start.
