how to make money from google adsense

Tweet

is it possible to cheat google adsense to make extra money .i have got a way but not sure whether it works or not . few days ago my friend asked me to create a group for those persons who want to make money from their sites/blogs. he told me every member of the group will be provided with a link to other members site or blog and will be asked for few targeted clicks on ads and in return he can also submit his /her link to the group to get some money from his adsense .he is waiting for my permission .but i m not sure whether it will be legal or not .if google caught this type of tricks working they can delete the account of any suspicious person
