The world is replete with examples of why you should never use your real name with your online identity in any way (although in this case, the guy's employer found out over a photograph; which is even more troubling.) If there's anyone worse than Adria in this story, it's both Hank's and Adria's former employers. You don't destroy a person's life over a comment or a blackmail threat. But as they say, if corporations…
While I agree with most of your post I don't agree with this statement. In my opinion hiding behind a username not tied to your real identity is nothing more than a stopgap, eventually someone will link "byuu" with who you really are or more likely you will make a slip up and expose yourself. DPR did everything he could to conceal his identity while running SR and he still screwed up. Even if you don't make a mistake I believe that we aren't too far off from computers being able to analyse written comments/posts/tweets/etc and then link identities together based on writing style, posting time, and other metadata. It is because of this and the following two reasons that I nearly always post under "joshstrange".
1) I stand by what I have said and when I find out I'm wrong I like to publicly admit that. I'm not going to pretend I'm perfect, none of us are.
2) By posting under my real name I am less likely to say something that I will have to backtrack on, it would be a lot easier to spew off the cuff responses (which I'm still not perfect from doing) thinking that I was hiding behind some username that would never be linked to me.
Pretty much I think that one day all my other identities will be easily linked back to me so why try and hide?
