I’ve been using Fedi for a long time and from the very beginning I’ve been afraid of spam and bots ruining it, at least temporarily. Spam is still a problem with e-mail, and it’s been around for 40 years and they’ve developed very sophisticated anti-spam mitigations for it.
That’s probably just mail that lands in your spam folder without being entirely blocked. According to Microsoft and Google approximately 99% of incoming spam (of the ~160 billion spam emails sent per day) never even reaches their users mailboxes. I assume that’s roughly standard across email providers. I am concerned comparably sophisticated filtering may become necessary on the Fediverse eventually.
