This article is from the Dissociation FAQ, by Discord (firstname.lastname@example.org) with numerous contributions by others.
Do not post about potentially disturbing subjects without giving some sort
of spoiler. A spoiler is a caution/warning that the contents of the post
may be disturbing for a specific reason, followed by about 20 blank lines
to make up a page of text, giving people a chance to skip that note.
When discussing the reasons that one dissociates (whether it is
multiplicity or other forms of dissociation), it is sometimes helpful to
examine the events that led to dissociation (or, with multiples, initial
splits and later splits). Some people reading this newsgroup may not be
at a stage where they can handle particularly blunt descriptions of some
of the more common incidents that lead to people dissociating. So that
people can participate even if they have a number of unresolved triggers,
certain topics should be spoilered. These topics include but are
not limited to: sexual encounters (both positive and negative), all forms
of abuse, suicide attempts, cutting/self-harm, all religious topics
(both pro- and anti-), and integration/fusion. The fact that a topic is
not listed in this FAQ does not mean it necessarily may go unspoilered;
if several people request that a topic be spoilered, these requests
should be heeded.
Please note: although on ASAR discussion of multiplicity itself is often
considered spoiler material, obviously this will not be the case here.
