After seeing the pic of the now-1.5-year-old-frame, I'm pretty sure totoroben is just plain hard on his bikes, and he'd be having problems with whatever he rode. A V-Rex is a pretty sturdy bike, and yet he's destroyed one and is well on the way to destroying a second one. All those scuffs may not in themselves qualify as "abuse" but they're pretty indicative of the level of care the bike is receiving.
On another note, it looks like he's still got a too-small frame, and is reclining the seat so far that the seat frame is levered against the back of the main tube - possibly the cause of the first failure. Look at how the paint is gouged off the back of the main tube.
