Tower VIP program - anyone have more info?

[Toyboy]

Recently signed up with Tower. I've seen people mention "VIP 6x Freeloads" (I'm pretty sure), so I emailed support to ask what is takes to become a VIP. They said "keep playing like you do currently and our VIP manager will surely be in touch". So no info before you're invited I guess.

But I'm a curious guy, so if anybody here have more details I'd appreciate it. What it takes to become one, what are the benefits (freeloads I guess, but how often and what clearing rates etc)
