Sites that do not offer rakeback

[PTjvs]

I've decided to "take advantage" of the current party network mess to do some bonus whoring & non-rakeback affliate site boni. However, I don't want to make a big mistake & sign up for a non-rakeback account at a site that may someday become a good main site to play at. With that in mind, what are some medium-large sites that do NOT have any form of rakeback?
