TD and Lew are the same person. I suspected for years they were, and a bunch of stuff Lew posted in the months before he disappeared kinda cemented my suspicion. They disappeared from the forums at the same time.

People often confuse a person's writing with what they actually think and feel personally. I was pretty sure years ago that TD was treating the forums as his own private game, and adding a contrarian alter-ego in this forum is just an extension of that game.

I think he just finally got caught, perhaps was at risk of a ban, and he shut down both personalities to avoid fallout or an official outing.
