This Wednesday I'm moving the servers into a colo data center so they have a proper home, once that's done I'll be working on getting the archive up and some things that'll crosspost between Reddit>Lemmy to get stuff started.
Unfortunately there isn't a way to link them that I've found (yet). Usernames might not be identical and such too. The script injects the old data into the BeyondCombustion.net Lemmy SQL database directly all under a fake/bot account name, or Redarc displays it in an HTML/webpage format like in the example link.
It's mostly to have a way to post the entire back content which came up on Google searches for people new to vapes or, "vape curious" as one might say. There's some cool DIY projects, health related stuff, general neat history that would be a bummer to lose in /r/Vaporents.
Reddit had threatened to take the sub down due to links and stuff going to vendors or people wanting to sell used vapes for the last couple years. This is a way to hedge the bets with that content so it comes up in future google searches down the road and helps out those who haven't moved "BeyondCombution" hehe yet.
So you would put it under a different, archival community? That doesn't sound like a bad idea. We don't know that it will last on reddit, and it opens up the content to be accessed outside of reddit. It could draw users to FC and to lemmy.
On the other hand, starting fresh can be nice. The archive is inseparable from reddit and their influence. One example: All of the posts in the archive abide by reddit's admin rules, and it may not reflect the opinions of the mods/maintainers/community. So this could also be an opportunity to hit reset.
