frankly, yes? the reddit admins didn't care about anything, really, and very rarely went on banning sprees. when they did it was just deleting subreddits that were regularly posting about wanting to kill people. and in those cases it didn't require thousands of other random people who just happened to be using an instance but weren't part of that stuff to create a new account on a different website, it just got rid of that one community.

the real problem isnt always your local bofh, it's the other bofhs, and it's the fact that your friend's local bofh who has a tiny fiefdom of a few thousand users can unilaterally cut off access between those users and the few thousand people on your instance.

i'm not going to go so far as to say "centralization is good", but in a centralized system, a personality clash between a couple internet janitors might lead to a new subforum being made that a few users might choose to go to. in a decentralized system, a personality clash between internet janitors leads to platform-wide technological incompatibilities for thousands of users who have nothing to do with it.
