To the best of my knowledge, I was speaking to all sites not just US friendly. I'm sure there are some new or unproven sites that will still do what you're seeking, there just won't be very many and they won't be large sites. The whole point of the bonus money is to make you earn it so that you play at their site.
I was just shamelessly noting that if you choose a more traditional site that we have many bonus codes available and those help to support the site.

But again, I don't know nor have I investigated all of the sites out there.
Probably because nearly all sites that give any sort of bonus also put an expiration date on it by which you must earn it. That way they not only "force" you to play on their site, but also to play enough to clear your bonus. Plus, if they gave it to you right away, that is more money you could simply lose and walk away from leaving them with no legal recourse for the most part. Making you earn it protects them.
