> Excuse my ignorance but how will the fediverse defend itself against email spam? That's a good question. Right now there's very little stopping people from spinning up some ActivityPub server and blasting out messages. I'm actually surprised at how little ActivityPub spam there is currently. One of the awesome things about the fediverse is how anti-commercial it is right now. Maybe it's not a major target for spam because there's not a lot of money in it.
