Indeed. But what can they do? If this software does what it says on the tin, how do you detect something like this, particularly if your site attracts a big number of legit clicks?
A rather large company (no names mentioned) got caught out like this recently. They were using a click bot which came in from various different IP addresses. Luckily, the company that was paying them, had a bright spark (quite possibly the only bright spark in the company IMHO but we won't go there

). Said bright spark realised that even though the clicks were from different IPs, the spread of the clicks and the ad rank was too uniform - in fact, it was exactly the same every day (ie every Monday's data was exactly the same, every Tuesday's was the same etc etc). So, the 'middleman' company refunded their advertisers for a couple of months worth of dodgy revenue. Congrats to the analyst who found this - I personally think it was a nice piece of detective work. However, the revenue returned was a tiny, tiny fraction of the click fraud that goes on and barely made a dent on the fraudsters income.
So the discovery was great, but there are 2 major problems:
1, There are a myriad of ways to get around this sort of analysis so that it is well and truly undetectable.
2, The analysis hasn't happened again. Partly because it takes a lot of time and resources and partly because it makes the middleman a lot less money (they don't get the cut). Plus, it's hard to prove - after all, they *are* all different IPs.
Could it kill the PPC industry? In short, yes. If you were guaranteed a 5 figure amount a day, would you take it? If your domains started doing badly, would you be tempted? Honestly? Me personally, I like to make my money the legit way, but I can see the temptation. The first question is - how do you stop the fraud? The second question is - how do you persuade the big companies to implement your idea? (bear in mind that they are getting a cut of every fraudulent click. So why would they want them to stop? Would you like to be the person who is known for cutting your company's profit margin by double figures?)
In all seriousness, how do you detect and stop the fraud? I can't think of anything that could really...would be interesting to hear if any of you have any ideas
Okay, I've gone waaaaaay off on a tangent so I'll be quiet now
