One should really read more before they make a post.
I would encourage you to read more before posting. Again, as I said before, please read through the thread at [webmasterworld.com...]
As well, while I realize it might surprise some people, in fact, I would recommend that any such person now sit down as I share this "surprising" news for them. ... -- Not every keyword is a COMMERCE issue. Imagine that!
I admit that it always amazes me at how quickly people forget that the original idea behind the development of the internet was a way for INFORMATION to be available to searchers -- not to be a mere avenue of cashflow for irrelevant non-comitted affiliate advertisers.
The issue is not about "complaining just to lower costs" or "fearing competition."
"Drive by affiliate ad bid atacks" come in and eventually go, but then they are then followed by another and another, adding no value to adspace and only costing the long-term advertisers more than the keyword is worth. So the issue goes beyond a single unaccountable anonymous affiliate ad. In my keyword, their ads fail, but then the next one comes along until it fails too -- all destroying the motivation for the user to even bother looking at the AdWords adspace.
There are so many other issues too, but I will let you read the thread instead.
