Oddly enough, I believe he WANTED us to know.
If you examine the posting history of "titanmike" you'll see that he copiously sprinkled clues to his identity. He wanted us to know it's him.
Now, you might wonder what would cause a person, whose very presence here as a previously banned FReeper is in violation of the rules of the forum, to intentionally leave a trail of bread-crumbs that give away his identity. I can only guess as to what sort of psychopathology leads to that behavior.... my guess is that it has to do with "attention seeking behavior"...
