@dansup my opinion:
Why do people that think automated blocking is a good idea even use federated software?
It's like with E-Mail. You host your own server and suddenly find yourself on a zillion block/spam lists because the server is new and therefore "suspicious" and you have to jump through countless hoops with countless vendors just to send a single E-Mail.
@lerk It's not automated blocking, it's just a list of "potential" spammy instances.
There are quite a few "abandoned" instances that are a haven for unmoderated spam and this could be a way to identify problematic instances in this context.
This is not like fediblock, and isn't meant to suggest instances to block, rather its purpose is to help admins identify this specific (potentially) spammy behavior.
It's just an idea for now, and feedback like this is crucial to direction it may take!
