Great post, but here are some questions those graphics raise, that I couldn’t find an answer to, and which have only my experience with email, usenet and irc for reference (all of which are federated, easy to abuse, had a host of problems, and have slowly migrated to centralized versions to solve these issues):
how do you ban someone?
what stops him from spinning 100 amazon ecc instances, federating 100 servers and spamming his thing 100 times from 100 different instances?
how do you even block an instance?
what happens with the federated content once the source instance goes down?
say lemmy.ml and memes goes down, how do you post a new reply in memes@lemmy.ml? does it even work?
i haven’t found any info for syncing accounts across instances (to prevent this loss) or if this is even possible at low level
what happens with comments and pictures once a federated instance goes down? say, if i selfhost and i crash without backups, does my content and posts disappear?
can i pull it back?
what kind of capacity planning would I need to selfhost say, a decade worth of reddit browsing? assuming I only care about my posts and what I save, would they be accessible for me?
