Interesting article in today's Inquirer, Business section, about the internet add-clicking fraud scandal, and what a problem it's become. It's to the point where scammers are hiring off-shore cheal labor to sit in front of a computer all day and click on ads.
THIS IS NOT A THREAT TO GRU, I HASTEN TO ADD.
The reason I mention it is that it talks about the revenue explosion tied into AdWords, and specifically regarding search engines, growing 30-fold from 2000 to 2005. ($222m to $7.5B, I think, if I remember the article correctly). It's not meant to pump GRU, but rather to generate understanding of GRU's potential in the event that it can align itself properly in the search business. If GRU is the real deal, and I admit that this is one thing that I am unable to grasp completely, the sales potential is unfu***ngbelievable. I would love anyone to search this article in Today's Business section, and comment on it, and on how much, if any, it speaks to GRU's niche. Article is entitled, "On-line 'click-fraud' cheats e-merchants".
Check it out, and check back. Can't give you link--I'm not good at things like that.
BTW now I know nothing of computers but i would think you could eliminate payment for any address that shows up multiple times since i assume you need cookies to make them work. I doubt that it is a super big problem that can't be fixed.
