Essentially committing fraud. The issue in this post is his AdWords account was banned because of x,y,z reason but not because of to many clicks. They probably saw the $100 credit beding used for affiliate direct linking and flagged the account.
Just as an aside I have 13GB on dropbox now and got the additional storage by using the technique outlined in the article. My biggest difference was that the account was seasoned and I was spending my own money, not google coupon money.
