In an ideal world, we could randomize servers in the Pixelfed app, however, there is a paradox.
The most performant and trustworthy servers are the ones who've been around the longest, and maintain good moderation, and performance.
Do we want to encourage users to join smaller servers with less experienced admins, or encourage them to join larger/more stable servers and support account migration so they can find a better long term home?
It's a tricky situation, but one we need to solve.
