Since you already distribute tools that help users enhance anonymity of data files like MAT. I propose we go one step further and distribute the opensource JSAN framework that includes the JStylo/Anonymouth. These tools carry out adversial stylometric analyses but also give tips to users on what they should avoid or change to conceal their writing styles.
This is important for people who have authored larger works under their real names on the clearnet under previous blobs, sites, academia and have decided to do large works anonymously.
