Rake rebate question

[Predator314]

I don't understand why these poker sites are against rake rebates. From what little bit I understand, it looks like they pay the affiliates the same percentage whether the affiliate is offering rakeback or not. Is this true?

Also, why not offer rakeback to long time customers directly? Let's say a site is paying an affiliate 35% of all my rake. He/she, in return, pays me 28%. Wouldn't it make since for the site to pay long time members 28% of their rake and bypass the middle man?
