Yes it matters, because if 90% of the clicks are fraud, then you are spending 90% too much money on advertising. Just because a company is profitable using AdWords doesn't mean that they couldn't be more profitable if the click fraud was removed.
Also, the cost of PPC advertising is going up. So while you may be profitable now, in a year, you won't be unless the click fraud can be removed.
Just don't bitch if there is a problem and you can't be contacted. Speaking as a merchant, I can tell you that e-mail is not the most reliable method of communication these days.

The sites cover a wide variety of topics, none of which are "geek-centric."
I control many sites with hundreds of thousands of visitors a day. Here are the stats for search engine referers:
google.com (54.8%)
yahoo.com (10.3%)
msn.com (4.2%)
aol.com (2.3%)
ask.com (1.8%)
disclaimer: MSN and Yahoo are inflated because of Overture PPC traffic.
