It was indeed changed about 5 minutes after he posted. But it also links the source, which is correct:
"Q: What happened to all of the Scourge’s Obsidian Destroyers?
A: The entities known as obsidian destroyers are actually enslaved titan constructs that were once called the tol'vir. The tol'vir were created to maintain titan lore repositories and titan machinery surrounding the titan cities of Ulduar and Uldum. Not long after the troll empires divided the insectoid kingdom of the aqir, the aqir that travelled north discovered and overthrew the tol'vir society in Northrend. These aqir would eventually become the race we know as the nerubians today, having adapted the tol'vir's architecture for their own purposes. Similarly, the aqir that travelled south ransacked and overthrew a titan research station near Uldum, renaming themselves the qiraji and calling their new home Ahn'Qiraj. Although the Scourge would eventually consume the nerubian empire and throw its few remaining tol'vir slaves into the front lines, it's possible that more tol'vir still exist in the hidden titan city of Uldum or deep within the remnants of Azjol-Nerub."
