I agree some people do anything for money, but it is quite sad that they would drop so low especially when they look to have established quite a successful site already.
It is big time cheating and Google does read forums like digitalpoint frequently. That is where I followed a link here.
I believe it has already been reported and they did take their adsense down.
the owner of that place has no morals, i regret joining. . . you get e-mails from him all the time and he ALWAYS mentions that he is running the forum out of his own pocket and he's spening lots of money on it to keep it free for us and if we think we can 'help out' then to let him know. . . all he is trying to do is get people to give him money for no reason, my advice stay away. . .
Don't worry google is too smart. He will catch him very soon
Google runs the bot every few days to catch these cheater and this bot is learning new things every day
