Heads-up for admins of instances hosted by toot.io 📬
We saw a coordinated spam wave: one actor signed up on dozens of our Mastodon instances at once with the same email address (plus tricks like name+1@…). The result was a flood of confirmation emails to one inbox, which hurts our mail reputation for everyone.
Fix, now live: each email address gets at most 3 confirmation emails in 12 hours, across all instances that use our mail delivery. Every message after that just gets dropped. Normal signups aren't affected.
