Just checked. Threads are gone - could be by him or mods. But his last activity was just yesterday, and still has over 4000 posts. It's just his threads.
I get it. Sometimes you just want a fresh start, or want to erase that crap out of your life. I deleted my original thread at one point, then asked the mods to resurrect it later because I wanted to go back and remember where I was at that time.
