I saw this coming up more than once, not only on the forum, but also on various threads on reddit.
Personally I don’t see a way how to integrate actual references from Couchsurfing™ in a trustable way. The issue I see is that at Couchsurfing™ they had a lot of marketing talk about the importance of references to contribute to a safe platform. But when you look at how they implemented it, you’ll see that there’s nothing supporting this claim about references being especially important for safety and security. They are stored as plain text alongside any other information you had on your profile. Once you download your data and references from Couchsurfing™, they won’t even trust these references themselves. Because anyone can edit these plain text references to say whatever they like.
But as said, this understandably comes up often as a feature request. Maybe there’s a different solution or other ideas how we could give credit to previous experience as a host and surfer!?
