Yahoo! Article - Click Fraud Rises with Online Ad Spending

Nice article that is very interesting to those of us in the adwords world.

I heard a statistic the other day that online ad spending is now up to the same expenditure (and soon to be exceeding) the amount it was before the dot-com bubble burst.

I guess that naturally with the increased rise in online ad spending comes increased fraudulent representation of ad effectiveness. Have faith though, it shouldn't be too long before someone comes up with a technology that identifies fraudulent ad clicks.

In fact, the article even mentions a few emerging technologies although it sounds like they're not quite there yet.
