Bodog Rakeback

[usi34]

Ive searched the forum and read all the posts about Bodog and Rakeback but I still am wondering.

I play 2/4NL, 3/6NL, and 5/10NL for about 3-4 hours a day. I am constantly withdrawing and redepositing money to take advantage of the bottomless bonus.
Here's my questions.
Is rakeback available at Bodog for someone who already has an accoun? Would I need to make a new name from a "clean" computer?
How much more would I make with rakeback compared to just clearing bonuses??
Thanks a lot, J Hoov
