How do I stop a hacker from using acronyms and automations to label my files on my computer?

SSeriously, I have a hacker who is using acronymic letters to label certain things and files of posts and letters that I write and threatens DC with these letters. S/he has gone into the software of the computer and creates automations of files and labelings. It's like a bug in the predictability of words and file names. Another way for communicating with multiple persons reading an open thingy... or doc or words or file...
