Really. Fighting Anonymous is like fighting an omnicent and invisible monster. You don't know who they are, where they are, and you can never hurt them. Not enough of them to make a difference anyway.
People always go around arguing about whether Anonymous is good or evil, but the answer is NEITHER. Anonymous is a force of chaos. They love overturning order, because they think it's funny. This makes the order people pretty nervious.
This is incredibly stupid. Whatever your feelings toward the *group* anonymous, anonymity is a key part of the internet.
