- There is some differencies between blacklists database and API to protect against spam bots registrations/comments online. Blacklists show all history of spam activity, but our API (that used in spam tests) used another parameters, too: last day of activity, number of spam attacks during last days etc. This mechanisms help us to reduce number of false positivitie. So, there is nothing strange, if some emails/IPs will be not found by bulk comments/accounts test.
