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 die inside every time I see discord of matrix used that lol. I feel like homelab users have more than enough processing power to run their own lemmy instance or maybe a forum. The beehaw situation really isn’t good. I suppose you could use lemmy like a forum though? I hope they get something sorted out though.
