Here is my attempt to archive r/homelab before it went dark. Google says there about 92,400 results for site:reddit.com/r/homelab, I have 2098, that’s only about 2% of it. Maybe there is something of use to you in that 2%.
Please don’t webscrape, if you want all the data you can get the raw BDFR archive at https://archive.douwes.co.uk/reddit/homelab.tar or the live web version at https://archive.douwes.co.uk/reddit/homelab-web.tar
I’m not saying we would go down the lemmy.world route, but equally it wouldn’t be a home server, there are more reliable options, lemmy.world is struggling a little right now. For moderation I was specifically referring to the tools available to moderate the community, automod on reddit is very powerful and helps take the simpler tasks out of moderation that stop subs becoming spammed and botted messes, the API is very useful for moderation bots and there are some other useful tools, Lemmy isn’t close yet and will be a while off…
Edit: Sorry and yes I’m not a fan of discord either, it’s not got the knowledge retention like a reddit format where you can go back and pick up on a 2 year old conversation…
