Breidbart Index

/bri:dbart ind@ks/ A measurement of the severity of spam invented by
long-time hacker Seth Breidbart, used for programming cancelbots. The
Breidbart Index takes into account the fact that excessive multi-posting EMP
is worse than excessive cross-posting ECP. The Breidbart Index is computed
as follows: For each article in a spam, take the square-root of the number
of newsgroups to which the article is posted. The Breidbart Index is the sum
of the square roots of all of the posts in the spam. For example, one
article posted to nine newsgroups and again to sixteen would have BI =
sqrt(9) + sqrt(16) = 7. It is generally agreed that a spam is cancelable if
the Breidbart Index exceeds 20. The Breidbart Index accumulates over a
45-day window. Ten articles yesterday and ten articles today and ten
articles tomorrow add up to a 30-article spam. Spam fighters will often
reset the count if you can convince them that the spam was accidental and/or
you have seen the error of your ways and won't repeat it. Breidbart Index
can accumulate over multiple authors. For example, the Make Money Fast
pyramid scheme exceeded a BI of 20 a long time ago, and is now considered
cancel on sight.
