I'm not a prescriptivist, but my definition of "obfuscate" aligns with google here: to obfuscate means to render obscure, unclear, or unintelligible. By using different usernames on different instances, you are trying to render unclear the fact that you're actually just one user.
You've also claimed that you aren't [email protected], which is a very obvious lie. You could say that by using these different usernames, you are trying to render the fact that you don't run both accounts... Unclear.
My bad, I misread the comment. You weren't saying you had just found the thread when you left that comment, you were saying you had only just found my comment. So you are [email protected]?
