The reason I am asking is because the admins don't remove spam and the version they are using is old.

Which make me ask, why even open an instance on the Fediverse if you are not going to keep it updated and spam free?

Over the long-term this has the potential to harm the Fediverse and take money out of the other Piefed instance admins that keep their instances updated and spam free.

When will .world admins start caring about the Piefed instance?
