The only proven way that I know of to reduce JUNK traffic is to determine the source where your money is being TAKEN from [in this case Kanoodle] and pull the bids down on those KWs that are being targeted.
The "spam click" engines generally give the pond scum looking for 1 to 3 cents a directed search option suck as Games or MP3. It is less likely that these spam click folks will take the time to actually use the search function. Just don't bid on any KW that appears on the "spam click" engines pages.
I don't have the time to get into it now but there seems to be a pattern of ownership [at least by industry background] that runs through these "spam click" engines. Dig around and you may see what I mean. [searchprograms.com...]
imho
If you are advertising with Kanoodle and don't want your listings to appear on any of the pay per click search engines that pay it's users to search or click then you can turn it off.
In your Kanoodle account simply choose the "Sales Driver" program rather than "Brand Builder" and your listings won't appear in any of those search engines.
SearchCactus is another pay per click search engine that pays people to visit listings.
Hope that helps.
