There is no public information about that, not for SURBL since its not a 
per default pick. Any domain can get a specific listing criteria. So there 
is no such thing as you mention above. Not for SURBL at least.

Some entry's will never expire for example.
This has nothing to to with beeing fair.

We have various ways of testing accuracy, SpamAssassin mass checks is one 
just of them.
