I have followed these lines of thought before. They contain a fatal mistake.

Anonymous is not a group that can have a reputation. At best, it's a subculture. Anyone can call themselves anonymous. Whoever didn't lie in all the previous incidents may not be behind this one - this could be a totally different person or group of persons with totally different ideals.

Cultures can have a reputation. They can also fight back when someone uses their name for something they disagree with.

That's an amusing statement. The whole point of anonymity is for your statements to be judged on their merits rather than your reputation.
