Edit: emailed this person, told them to be more careful about what they upload to the server. Thanks for the advice.
Long story kind of short, I found a strange file on the server at work (Arabic file name, company working language is definitely not Arabic) opened it up (I was intrigued by the cover illustration) and after some translating I discovered the book was The Manipulated Man. Checked the file properties, I know who uploaded the file to the server, but I have absolutely no relationship with this person (besides working for the same company).
Where you tankie bastards come in:
Should I do nothing?
Should I confront this person? If yes, how should I confront this person?
Maybe send an email then. Uploading any personal content to a public server has always been frowned upon at places I’ve worked so it’s not crazy to contact the guy—especially if your job is in anyway related to network security or other IT type work.
