Mail messages with total or aggregate target counts larger than 10 are bulk and so "likely" spam. Messages with target counts of millions or "many" have been declared spam by at least one DCC client. The "Spam Ratios" are of "likely spam" or "trapped spam" to the total number of messages. DCC client programs can reject or discard bulk mail that is "likely" spam as well as "trapped" spam.
Graphs of the size of a DCC server's database and of "flooded" checksums are related to the total spam in the Internet.
