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?

I hadn’t responded in this thread immediately for various reasons, but just so you know: We generally do. I banned the first instance of that spammer a couple of days before they came back. I wasn’t around when they created the second account, but it was only in existence for a couple of hours. They haven’t yet come back again. :)
