I think a reasonable solution to dealing with spam account mitigation is to build out and embrace user level invites
Allowing users to invite their friends and leveraging their "trust score" to apply our Autospam detections accordingly.
This would solve the UX issue, while still allowing for strict vetting of new users.
What do you think?
(Boosts & feedback greatly appreciated)
@dansup I agree. not bulletproof, but effective.
