|Attrition does *not* encourage web site defacements. We merely report it. Why does a reporter on a crime beat write about rapes occuring in a particular neighborhood? To encourage rape? Of course not. It is to inform the public that the neighborhood isn't safe.|
Statistical Obscurata: Misleading statistics caused by other factors
such as public release of exploit code (wu-ftpd, etc), ease of
exploitation (unicode, etc), mass hacks (some virtual servers), and how
it relates to OS stats.
Statistical Skew: Indiscriminate defacers, hoaxes, mass hacks, popularity of an OS, deployment of OS and Web Server, munging of a family of operating system (BSDI, FreeBSD, OpenBSD, etc), and more.
