Dwarf Rogue BOTS being created by the hundreds

I created a level 1 Dwarf toon, once entering the game in the level 1 spawn area, I noticed hundreds of Dwarf level 1 Rogues being created. All of them with random letters in their names. Watched the creation for over 25 minutes, until it just stopped. All ran off in a Bot formation for 20 yards and disappeared. Not sure if this is happening with other character races. Took screen shots of it, if Blizzard is interested. Craziest thing i have ever seen.
