I think Bipolarbob has left for another forum long long time back. There are many people here who received his love with free or super discounted gift card, some dude even created a thread when he got a 50$ gift card for just 6$ from bipolarbob, and bipolarbob's funny puns were really nice. Some guy advised him that he should get an avatar and he responded back saying,'I liked the movie but I don't know what the big deal is' 
Well atleast he still made a great giveaway thread few days ago that gave $5 for first 100 posters 
He is a nice guy who like to help other person, not to enrich someone.Yes, I believe I have also encountered the gift certificate giveaway contest by bipolarbob, it is very rare to meet nice guys which can happily give away their money in exchange of satisfaction from happiness of others. He is a very nice guy and I wish the best for him, and I definitely hope I am blessed enough to encounter such similar people for the rest of my life.
