@okpierre I think this is good and fair, I mean anyone can host their own instance, you just need less than $10 per month for a vps or a 8GB Raspberry Pi that runs it at home.
So no need to worry about paying for accounts.
Besides that, hosting big servers costs a few hundred $ a month, so it seems fair to have an accounting option built in to the server software. (Which I assume this features are from?)
