Anonymous

Ok, here's the basics: Anonymous is a hacker group that reportedly originates from 4chan. There is no known hierachy within this organization. It started out as a group of childish pranks, but then....

Scientology

In their first major action, they:

• bombarded the "church"'s website
• redirected google search so that they show up at the top for results of "dangerous cults"
• And took up the V for Vendetta mask as their symbol

Anti-IS action

This action earned them global fame. And honestly? Well done! (info needed)

In modern days, trying to be a real-life vigilante more often lands you in jail than make you a hero. Anonymous' ideals are vigilante-ish, but their MO skirts the fine line of law, just like fantasy mercs. Whether as people to be admired or a nice group to model your modern-day rpg pc on, Anonymous is suitable.
