Hey @nolan I just read your article: https://nolanlawson.com/2018/08/31/mastodon-and-the-challenges-of-abuse-in-a-federated-system/
...and I had a question about when you wrote: "The spambots used various domains in their email addresses, but they all used same email MX domain."
Does that mean you had to block all accounts that registered using email addresses that ended in .mx ??
