I'm with advertmarketing.
I havent made any conversion yet..
I used Advert Marketing a while back, years ago, did nothing against their TOS, spoke with the admin a few days before payment about sending my w-9, sent it in, got banned within an hour of sending it in. I personally would say not, but that's up to you.
Close to the same story here only I was paid a couple times then banned after they damn near begged for more traffic, after I sent it all of a sudden the advertiser didn't like it anymore.
So for a long term use network I wouldn't suggest them. Not to mention unless it's changed they are net 30 which is ridiculous.
