I doubt Lemmy will ever do this - e.g. moderator reports still don’t federate to other instances until the release of v1.0, despite the Rexodus having been several years in the past now. Basically any solution would have to be on top of the software without needing any changes within it. Lemmy puts up full-page advertisements for donations but a lot of that funding goes to running Lemmy.ml and seemingly only very little to actual code development.
Although predictably PieFed already has this functionality, for well over a year now. For one it has hashtags, plus user and post flairs, and for another it has categories of communities where someone can look at e.g. news across all regions, or pick let’s say Europe and then choose from various sub-topics below that. Also, while these Topic areas are defined by the instance admins, the otherwise identical concept of topical Feeds are user-customizeable and even shareable, so someone has likely made what you are looking for already, but if not then you could make it and share with others to benefit from your efforts.
At worst even, say when interacting with existing communities that did not want to actively participate in the process of self-sorting their own content, users have keyword filters that can be used so that you as an end-user can do it entirely on your own. Such community discovery and management concerns are a solved problem on PieFed. I say this full well as someone who had the identical issue you described here when I was on Lemmy, and moving to PieFed solved it for me.
The developers are also extremely receptive to feedback, if you needed still more changes made to the code. I sincerely doubt that you will ever get a solution going using Lemmy - this identical (edit: general) concept has already been asked for many times over the years - but switching to PieFed should easily take care of it, offering multiple possibilities to make finding the content that you want easier.



It almost seems like the majority of content injects news and politics into itself - e.g. memes, comics, and the like - or at least it does happen super frequently.
One of the most active posts this week, in !Technology@lemmy.world, is https://futurology.today/post/10493000 - and just look at how little moderation it has received, with one of its higher comments (10 upvotes, zero downvotes that I saw) being:
And here’s one with 81 upvotes that I won’t even repeat here but just offer a link to, as it calls for murder (Luigi-ing): https://lemmy.world/comment/24053139, among many many others with tens of upvotes that call for the guillotine.
Or another post is https://futurology.today/post/10503178, ostensibly about memes and from a science-oriented instance, with comments such as:
This one about the sitting USA president.
But I, like you, am here. We must have thick skins, or else we block content that we do not want to see - which someone browsing in guest mode won’t be able to do, at least not until AFTER they’ve made an account, and then learned how to do so. You would have to go to Reddit to ask them why “Out of the tens of thousands of people who’ve read our posts about the fediverse site, only a few hundred have signed up.” Surely it won’t be a singular easy to understand reason, but a plethora of them. Among which is how much of a turn-off this place may be specifically to an American centrist or right-wing, possibly even Trump supporting person.
