I think these topics with mysterious titles and just a random link are very annoying.
The rest was already said, there is not even any valuable evidence in this "opening post". (while there is a limit of wow accounts per bnet account, this limit has not been reached by shown player).
Confused. Is that one person? Maybe the accounts are battle.net linked so they all get the mount when one buys it? Is it different people? 2mill gold isn't much
