Some people do see them and some do not, it depends on a verity of things such as browser and any ad blocking add-ons you may have. I see the banner on my mobile phone but not when I am using my lap top!
Like I stated, some see it, some don't! Fact is, it is there and I don't agree with it. I am a fully paid up member of the AWS, So I am limiting my input in response!
