Find at the bottom where it says "Chance of Displaying Advert. (0-100)" and enter a value of 101, and save.
I hope you
have done this, just to see what kinds of ads are being shown to visitors.
So far, most of the ads I have seen look just like the following:Google ad test
A big download button with no hint of what it is actually for, that could be easily mistaken by less savvy visitors for a download button of some DC app, if it appears in a thread discussing one, and they are unfamiliar with the site, as would be the case with a first time visitor coming here from clicking a search engine result.
But what is it really for?
It leads to a site with a bit less than a stellar reputation: http://www.mywot.com...d/downloadangels.com
Not really too much info there as to exactly why, until you visit the site in question and notice all the "uninstall" links all over the place and check the reputation of the site they all redirect you to: http://www.mywot.com...recard/mindspark.com
Ah, yes, nasty, nasty toolbars, known worldwide as adware/malware/spyware.
Might want to at the very least, add that one to your adsense blocked urls list. I'll give you the exact url on IRC (you'll need that to block it), next time I see that ad.
