I don't see how you're going to catch people like this without doxxing them. They rely on opsec and misdirection to avoid getting caught. Do you have examples where the information was gratuitous?
When the has-never-been-sealed Federal Grand Jury indictment that the article links to has the fellow's full name and alleged area of operation during the alleged crime, is publishing their full name in your article doxing them?
If it isn't, is providing screenshots of their publicly-available Facebook profile photos doxxing?
Is providing the presumably-willingly-given-for-publication name of the person's mother who you performed an on-the-record interview for the topic of the article doxxing?
Is it doxxing to provide details from previous investigative articles that you've done into folks who use their handles to credibly publicly declare that they've committed noteworthy computer crimes?
