idk it's my first time (kind of) trying to do dataviz, I thought the original post was super interesting but like other comments said, it was hard to read.
I think in a way it's mostly because defederation is complex to show as links, since it is the break of said link, but hopefully this type of graph is better ?
you do lose the "group" of instances view, though (and also I did not bother with per instance MAU as raw number + percentage, or sofware used)
let me know what you think!
Not so easy.
Mostly a liability issue.
First there's security - make sure the server doesn't get compromised.
Then you need to figure out how to deal with illegal content like CSAM (was already a widespread issue on Lemmy at least once, causing multiple instances to shutdown) - even on private instance due to content caching.
And legal issues such as minimum age and privacy regulations that you'd have to comply with.
3rd one is not an issue if you only use it yourself, and perhaps with a couple of friends that won't try to sue you when they get mad.
