well said! I think you hit it with unfair adverts and affiliation techniques. Zango should be frowned upon even more, and I don't think Google plays any part in it, but I wish they would put their famous "This site may harm your PC" line on every site that has Zango.
yea, i agree, people dont want to promote zango cash and they try to stop other from making that income
by checking the referrer you know where the visitor is coming form: SE, direct or a referral site. Then you have to decide whether to display the popup or not!
Very true, excellent post i have tried zango on my computer without a problem. As you said my visitors come back and it actually helps my serp, and my earnings have not dropped but actually increased.
