SLDT was a contributor to Topix. He was a very intelligent poster who arrived around 2008. He was known for being anti-religious.
Because he insulted Christians, Wilferrel disliked him, and attempted to argue with him. At that point, Wilferrel was not a very capable debater, and was smashed by SLDT. Flame wars began between them, and Wilferrel began creating spam threads in which he took his anger out on SLDT, leading to criticism by other users. This caused him to abruptly leave the forum. SLDT also left at around the same time, however.
