it certainly is not futile. it's futile to try and hide. what's not futile is to spray out false information that muddies the real stuff. if OP wants to obfuscate his real name, he can associate his username with 3 different false identities, a throwaway phone number, a false nationality, etc.

obviously it's a little paranoid and arrogant to assume that anyone cares enough to go through my comments, but occasionally, on websites like this and reddit, I will just outright lie about where I'm from, or what my age or gender or ethnicity or sexuality is
