Anonymous isn’t a formal organization, it may have American members/participants but they could just as easily be anywhere else in the world and likely are.
They are pretty close to being, if not completely being, anarchists. They were big OWS supporters and agitators.
I don’t view them as loyal to a person, party or platform so much as they are like any other anarchy supporter or free market destroyer. They are only concerned about their publicity and attention.
If this attack is truly only from one person it is some guy sitting in a hotel room somewhere in Asia with a belt around his neck engaged in auto-asphyxiation, masturbating while wearing a cheerleaders outfit while reading stories about his attack.
Is it just a coincidence that two out of two candidate sites where I tried to make donations today were “server not found”?
I believe we can count on more of this until election day.
