So this is the third time I've brought that up. I should probably specify I'm willing to do all the necessary work myself, I just don't have any money for it.
So, there's people that have used the Reddit API to make basically a backup of it. If you could get a copy of that, you could very likely translate it into something Lemmy can read. Then, you go somewhere with protective laws in case Reddit gets involved and set up a special instance that just serves old Reddit content.
Afterwards, to re-use an example from one of my earlier comments here, you could seamlessly go to [email protected] and see u/CanadaPlus101's post about metal and aquatic aliens.
The trick is just hosting it. I don't know how much data that would be. I guess it might not be too bad since it's just text. Again, if anyone wants to fund it I'll make it happen. Otherwise we'll have to wait for the next person to set it up.
