One of my friend tried to apply for google adsense after getting banned. I told it is not possible to get admitted and ask him to look for google alternatives. He argued that there are few peoples re-admitted by google after getting banned. Is it really possible with google?
I have heard of people being readmitted to adsense, but they do need to show that they have mended their ways and their websites are totally clean of black hat SEO etc. Also: the case would have to have been light anyhow. Meaning: massive clickfraud is less likely to be forgiven then something that looks like clickfraud, but can be explained in another way. For instance: a lot of clicks from one IP that was a school or something.
