i've heard that if your already signed up with a site like full tilt...playing cash games even though you've never deposited (via freerolls) that you are ineligible to apply to any rakeback program? is that true?

i didn't even know much about rakeback until i actually started playing and now it seems like a very decent deal (27% back versus zilch adds up)

if ineligible...would I actually have to change my mailing address, IP address, new full tilt account, etc...to potentially apply then? I've only been playing freerolls for about 6 weeks...had done okay but recently busted out my small bankroll I'm just thinking that to start over again, I might want to do it the right way and get with rackback if I can.

Any thoughts?
