Ok, here's an advice.
With current way of faction making, you'd better don't do it at all. Instead, apply into [HF] faction. I'm pretty sure they'll accept most of you. And then the magic will be done. A couple of enthusiasts in zombie(correct me if I wrong) faction can easily become leaders within 2-3 months. But first understand one simple thing. Hellfire Legion(aswell as Red Hessians... more or less) are not about piracy or harrasing civilians. It's about killing mostly military targets and RPing you're doing it for the Greater Good.
