For anyone emailing lotto-investor for numbers be cautious in paying for his predictions (if he offers that). I've seen a few people post that he has scammed them. Only person I can personally vouch for is @ineedahit although he doesn't do predictions he does give pairs which tend to hit.

As @bmehmet always states don't pay for predictions until the predictor accounts are ready but at the end of the day everyone has free will.
