Actually the majority of discussion threads on these pages have five stages:

Denial, Anger, Bargaining, Depression and Acceptance.
.
Threads are habitually taken down this path by commenters who dwell in an idealistic dreamworld and take umbrage at anyone or anything that dares challenges their beliefs. 
.
Comically they use the @ symbol to give their comments some mythical gravitas.  In Dutch is is called the it is called the apestaart which means "monkey's tail" because it looks like a monkey with his tail curled over him.
.
The symbol perfectly depicts those commenters who wrap them themselves in their misperceptions and ignore uncomfortable reality...never daring to venture to Stage Five.
