What people don't understand about running an instance:
You're not just hosting content for accounts on your instance.
You're hosting content for EVERYTHING that federates with you.
My Pixelfed instance only has 8 accounts and less than 1,000 image posts.
I have 50 GB of disk space, yet I'm at 80% capacity.
As the Fediverse grows, federation itself requires more data.
Look at this graph to see what's happened during the past 14 days on peerverse.space
For 6 solid months, only 40% of my disk capacity was used.
Then when the #TwitterMigration happened, it slammed my Pixelfed instance hard.
Doesn't matter that it only hosts 8 users.
It's still a node that redistributes content across the Fediverse.
