Biggest scam of your life?

Before this i took part in scam program that i do not know that it was a scam!I hardwork for them and make small money.Then it quiet and ask me to pay for upgrade.The site name nric.com or what so on...i dont remember too much,waste my time....

Today I realized that both main-bux and 70cents are totally scam. Today I reached $2 in main-bux and requested for payments, but they said me to try later. also in 70cents. when gave the username and pssword and wasloging in , it said "invalid username". I tried so many times, As I logged into that site everyday, i am 100% sure i did give in the correct username and password. But still to double check again, i input my email add to request my username and pasword again. It was unbelievable that it said my email add is not in their data base. To chcek if something was wrong with their data base ,I registered again with them giving the same user name,password and email add which i used when registerting for the first time. It did accept my second registration, user name as valid. Then what happened to my previous records in their data base. If the probs was with their data base, how did it accept my second registration. I feel so down, coz I though i can atleast see $2 in my alertpay acount from main-bux. all in vain... Its depressing. but what to do????????????????
