fediverse.space relies on Mastodon's public timeline API, which is getting locked down in future releases.
This is a positive development for security on the fediverse, but it means that this project won't be able to access the information needed for the map of the fediverse.
One potential solution is to use a follow-bot. If a fediverse.space bot followed you, would you block it? (it would respect #nobot, of course).
I'm the joke, but you're the punchline.
I run this website. I like posting funnies and fugging lolis.
