Got any stats on how many times a domain has to be reported before it has a very low chance of being seen as a FP?
I don't have stats. IMO the first FP report is too many, and it probably means there are other similar FPs not being reported.
No, no - I mean, can we determine whether a domains is less likely to be considered an FP if multiple people report it? Therefore, scale according to the weight given the reports?

The AbuseButler data seems to have had a fairly low FP rate in large part because it is based on weighted reporting. Only the most frequently reported domains make it onto the list. It isn't perfect and there have been some FPs (mainly on very popular brand name domains that are misreported and get past whitelisting). If other folks want to pass along their URI hits to help improve the volume ratings feel free to drop me a line. At the moment weighted SpamCop data is still the largest source of data, but private trap data volume is growing.
