I've been using chrome for years and this is the only site I've ever had any issues with. Chrome is the biggest browser in the world with nearly double the market share of the next closest browser:

Just saying that its chrome's fault and there is nothing you can do is absurd. The reality is it's a vBulletin issue caused by a bug in chrome, they are too incompetent to find a workaround, and you have no control over your own software.
