So far "nigerian email spam" was easy to recognize. Grammar mistakes, bad translation, very bad wording... But now every fringe group, can generate gigabytes of text and arguments that make sense! This is the end of debate, consensus and interactive communication, as we know it!
Similar moment was in Africa in 1960, after they got AK45 and other cheap weapons. It was easy to dominate Congo River Basin with a few Maxim machine guns mounted on boats, when opponents had only spears. But when every tiny village gets comparable fire power, there are no colonies!
