You can only vouch for someone once you've received enough vouches. That along with with references provided a good way to quickly gauge the character and trustworthiness of a person. To gain vouches and references you had to have invested in the community. Not perfect, but often good enough. Couchsurfing also had volunteer community safety ambassadors, but I think less people seem motivated to do that kind of thing these days. I think a lot of the oldschool Couchsurfing moved to BeWelcome and Trustroots
