That might defeat NLP-based analysis, but the use of obfuscation and the methods employed still tells you something about potential authors. If someone in an organization writes an essay disparaging that organization, but does so in an unnatural style that seems intended to defeat author identification, then you know that they're aware of stylometric analysis, and have created or downloaded a tool designed to interfere with assigning attribution. Depending on the organization, that might shrink the candidate pool more drastically than clustering based on sentence length, favorite words, or other linguistic quirks.
