Joe Wein has created a new version of the data which Raymond is putting into ws.surbl.org. The new version is 60% smaller and contains only domains that were added under an extensive and strict set of criteria which Joe devised.
As a result, the jw additions to ws are 60% smaller and probably a lot better in terms of false positives. The earlier cut of the data had included some domains which Joe had seeded from other RBLs and which therefore did not have the extensive checking which Joe's current process applies to new entries.
Joe used the seeding from other RBLs to initially populate his data, but the new data gathered purely with his own processing should be much better.
Bottom line is that the FP rate of WS should drop.
Does anyone have any current FP rates to share?
