The Mini-FAQ contains some background information and some frequently-asked-questions, answered very briefly, with clarity in mind. The Mini-FAQ is also available in French.
The full version contains the same questions (and some extras), along with a compilation of some of the answers that were posted to news.admin.net-abuse.misc. Both the questions and the answers in the full version therefore tend to be somewhat more belligerent in tone. The full FAQ is also available in Dutch.
