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
What kind of issues is .lm having right now? Why not using lemmy.world?
Their instance is hugely overloaded, I think I saw somewhere where people were being encouraged not to register there for now (I mention that as this sub is on .ml). lemmy.world is certainly a more stable server, however users registered on beehaw now can’t access it, this is a major issue I see with how Lemmy and de-federation is allowed, but also “homelab” is already registered there although not used, it would likely be my preference though and I have looked at it…
