I also received Spam in the Fediverse. From multiple servers, large and small. The topic is important as the Fediverse will scale and complicated because of the implied decentralized nature of it.
Hence, I expected a thoughtful discussion and comparison of existing work, work in progress, current research questions and transferrable work between the two protocols.

What did I get: Absolutely thought free, cheap instances of tu quoque and demonstrations of incompetence about the subject being discussed. Do better.

Which brings us to one the most important tools to combat spam in the Fediverse at the moment: The block function.
