Is there a kbin API to allow posts? I had a look quickly at the docs and could only see get requests.
I ask this, as reddit can be ‘crawled’ simply by adding .json to the end of a user or sub (https://www.reddit.com/r/voidlinux.json for example). It should be possible to copy vast swaths of reddit over to kbin to build some history here, as well as potentially sync the data from reddit over to keep us from FOMO.
The term you’re looking for is “bridge”.
I don’t know if one exists for lemmy/kbin/reddit.
