If relevant you can use an RSS reader* to subscribe to specific communities, for example https://kbin.social/rss?magazine=kbinMeta (there's an RSS button in the bottom right of every page, next to the theme/lightbulb icon)

I've also suggested RSS feeds for DMs/reports/etc., hopefully this will be added some time

*I use Feedbro on Firefox

Found that it was already suggested :) (and I gave it a like)
