 context:

 Why does CollecTor remove ContactInfo from bridge descriptors?
 Publishing the ContactInfo should not (directly) reveal the bridge
 location?

 use-case for that data:
 bridge group detection

 If plain publishing is not acceptable how about generating a random string
 replacement for a given ContactInfo string.

 That mapping contactInfo -> random id should remain static for at least 24
 hours.
