It’s fine to be up to the user. But it’s also fine to say it’s just a spam account and block it to save bandwidth. Easy for me to say, of course, since I’m already not seeing the content.

The cool thing about the fediverse is that no one really controls the whole thing, so I give a lot of deference to folks who want to run things their own way. Anyone with a strong option that it needs to be done differently can stand up their own instance pretty easily.

Or to summarize, you have a point but that doesn’t oblige the server to be run that way.
