Patience, my friend, I’m travaling off-grid lately

Cool, thanks to all contributers!!!

according to the documentation open and blocklist have open federation.

if allowed is not null, then the server’s federation is in allowlist state

this.

otherwise it’s open federation with or without blocklist

I would have to take a look, it’s probably outdated, there is also https://github.com/LemmyNet/lemmy-stats-crawler

You can query an instance’s API at https://lemmy.ml/api/v3/site

Playing instruments, gardening, chess, workouts

I totally agree, they have the most toxic userbase and the most ridiculous moderation, partly attracted and supported by the devs/mods.
Unfortunately, these instances are perceived as “official”, so, many users will be put off in the first place.
For this reason, imho the lemmy-project will unfortunately never reach a significant range.
