Well, the data sources that have a significant false positive rate are
going to count many things as "incidents" that are anything but.
If sending closed-loop, opt-in email is considered equivalent to
hosting a botnet command and control network... the data is
meaningless.

In the hope of not pulling the blacklist trolls out of the woodwork
I'm not going to be more specific as to which of those data sources
have noticeable false positive issues, but I'm sure you get my point.

Cheers,
