i sincerely do not know if supertube is a scam or not but my experience with them was not so pleasant. Supertube will ask you to register for free, but to apply for their job offers, you will have to pay or subscribe for a passcode. I did tried paying a sum of #500 for 10days passcode with my ATM card but it backfired. All my money was removed from my account, about #7,500. When i got to the bank, i was told that the money was removed twice (3000 and 4500) and Nothing has been done about it since then. So make ur choice my brother.
