Exactly what I’ve done. Set my settings to hide NSFW, blocked most of the “soft” communities like hot girls and moe anime girls and whatever else (blocking the lemmynsfw.com instance is a great place to start), and I use All frequently. That’s how I’ve found all the communities I’ve subscribed to, but frankly, my /all feed is small enough that I usually see all my subscribed communities anyway.
Interesting. I’ve been using XeSS lately, after seeing better results in DOOM TDA, but now I’m curious if this is worth using instead, and figuring out an FSR replacer on Bazzite to use this.
