Most of my friends know that I am always searching for creative ways to earn miles. However, I don't agree at all with the method that was suggested above.
First, Clickrewards has been very good to a lot of us here. They have enabled some of us to have benefited from earning free tickets much faster, an example would be the double bonus it offered before with United and American Express Starpoints.
Right now, the company is going through some tough times. I really don't advise any of us to try to benefit by "causing" further damage to a significant medium through which we earn miles.
