I found out that one of them RON ads is a pretty high payer, the mortgage one, at least on my sites. Considering the ads that seemed to appear in it's place when filtering. And, I couldn't get it to filter before, I had to actualy add the www. then it worked. But like I said be careful, you may filter out high payers.... because they serve other generics if you filter out the popular RON ads... so really, Why filter ? Basicly just use the targeting as close as possible
I am wondering about this too, bluegill_catcher. So, today I unblocked them all. I'm going to try it for a few days, and will report back. It wasn't easy (using Firefox). I could not delete them all at once - NONE of them would delete. What finally worked was - I deleted ALL BUT ONE - that worked. But then, I could not get rid of the one remaining, until I renamed it gobbledygook.com. That finally worked. After all, it's still early beta.
I've had mixed results. I have mortgage sites and pet sites so I can't block the mortgage ads obviously but sites like ftd and vonage I've been able to root out.
