/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.
