Adsense Revenue Sharing
The Think Bling forums have modified software (phpBB) to provide phpBB Adsense revenue sharing. Basically, if you have over 10 posts, then you will receive one half of all the AdSense revenue for your posts. (Obviously you have to enter your Google AdSense ID).

Is this ethical? Yes.

Does Google allow this? Well that remained to be seen. I fired off a cheesy email to Google. Here it is...

Here is the original email sent to Google.

Does Google have any current qualms about me showing adsense ads using
other people's AdSense ID?

Before any decision is made please just look at my points.
1. My site is approved to show Google Ads.
2. I have the People's permission to use their ID as they get the payment
(If there is one).
3. This 100% NOT a "You click on my ad and I click on yours" deal. This
is just a way for me to reward my site users.

I know that Google is very open to new and different ideas as long as they
are ethical. Seeing as how the same ad will get displayed regardless of
who's id is used, there is no difference Google's AdWords customers or to
Google itself.

Thanks for your time.

Here is their response...

Hello ,

Thank you for your email.

Currently, it is not against AdSense program policies to display ad code
from other publisher's on your sites. You can review our complete program
policies at https://www.google.com/adsense/policies.

The AdSense ad code on the 'Ad layout code' page is valid for any page in
any site that complies with our program policies. Please note AdSense
publishers are only allowed one set of Google ads (one copy of the AdSense
ad code) on each page.

We constantly monitor all of the web pages displaying Google ads. If we
find that one of your web pages violates our policies, we will notify you
and ask you to remove the AdSense ad code from that page.

Please feel free to reply to this email if you have additional questions
or concerns. For technical support, please email adsense-tech@google.com.


Sincerely,

Christine
The Google Team

So you can see, it is perfectly fine to give away you AdSense revenue to anybody who would like to use it. So now that you know, start posting!
