It’s my understanding that there is no algorithm. View only your subscriptions, only communities on your local instance, or the entire fediverse. Sort them however you want. Mix it up to find what makes you happy.

All that said, I personally would like to avoid seeing any account less than, say a week old. Maybe a filter coded into the interface would work.

Or rather, the absence of one.

I guess in a way you're showcasing where algorithmic sorting/grouping, when not used just to promote ads and increase profitability, can have a positive impact. Because they could for example be used to temporarily suppress exactly what you mean, and require a community to stay "active" for longer than a brief flare-up to start spreading wider and wider.

That being said, I find the lack of such stuff refreshing. You after all select whether you want to see "All" content, and even the sort mechanism.

It’s a complaint about the algorithm flooding my feed with so much content from one place that I’ve unfortunately blocked communities over this that I otherwise would have continued to run across and maybe engaged with in the future.

A neat feature could be the ability to snooze communities. I feel like that could help a bit with what might be considered spam (or generally temporary situations you can't be bothered with).

I've been using the 'Top 6 hour' sort, and it pretty much avoids most of those posts as they have no activity. Blocking the bot accounts that still show up is then pretty easy.

The algorithm definitely needs some work.

I have found sorting by "active" to be the best sort order. It seems to be mostly immune to concentrated clumps, though it is very slow changing.

Also, what's this lemmitonlinebot that's flooding my feed and linking to Reddit?

When I select 'New Comments', every 3rd (actually counted) post is 1 points, 0 comments. Lol.

This would be a solution if it worked properly.

I remember when reddit had to implement something similar leading up to the 2016 election, because the entire front page was spam from "the donald* or a few vocal left-wing subs, and it was putting everyone off.

The solution was pretty much what you described.

Set your default view to subscribed in user options to show only the sublemmys you are subscribed to.

No such problem on small instances btw.
