CouchSurfing
From TrustLet, a free, collaborative project for collecting and analyzing information about trust metrics.
CouchSurfing is a hospitality exchange website. There are several ways that people can indicate that they're trusting each other.
[edit] Trust systems
- References
- extremely negative, negative, neutral, positive, extremely positive
- Friendship links
- 1 to 7
- includes some information that is not shown on profiles
- Vouches
- yes or no, (almost) not possible to undo a vouch
- Verification
- this does two things:
- verifies that the name on the profile is the same as the member's name on their credit card
- verified that that mailing address is the same on their profile
- once verified members cannot change this information without starting the process over
[edit] Trust metric task: predict who should you contact
A trust metric can be used to predict which users is better to be contacted for the active user.
Example: Mary is going to Paris, the system (using a trust metric) could suggest her which users in Paris she is more likely to enjoy and to contact her.
[edit] Negative reference retaliation
- Bob is staying at Alice's home. Bob seriously misbehaves.
- Alice leaves Bob a bad reference.
- Bob leaves a bad reference for Alice.
Q: Who to trust?
This is a very tricky situation that probably requires human intervention and a good dose of mutual understanding and talking. Negative feedback retaliation is reported to happen on Ebay.
