CAPTCHAs and sign‑up quizzes annoy real people and barely slow down determined bots. As the fediverse grows, we need smarter, more humane defences, ones that don’t push away genuine newcomers. What creative, non‑intrusive ideas do you have? Trust‑based vouching, proof‑of‑humanity protocols, behavioural signals… what feels both effective and aligned with the open social web? I’m building a social media platform and I’d love to hear your thoughts on this topic.


I would recommend the invite tracking. Keep track of who invites bad actors, even higher order. If your friend’s friends suck, that should reflect a little on you. If no one has vouched for you, then you’re less trusted.
I used to be a member of a closed torrent site that operated on this principle. You got a handful of invites you could share (active seeders got more), but you were sorta responsible for the people you invited (your username was visible to all other users on the invitee’s profile) and could face repercussions if the invitee broke the rules.
