It’s not an instance, but what about https://join-lemmy.org/ ?

I sure hope people aren’t deleting all their old useful guides and troubleshooting posts. Yesterday I was playing Stardew Valley, I had a simple question, so I duckduckgo-ed it and found some promising links on r/StardewValley, but StardewValley was private. Very frustrating. I hope this isn’t the norm. So, so far…that. I miss StardewValley. Besides that, I will miss r/bestofredditorupdates
