George,
I wouldn't be too concerned with the negative reactions of some.
You did a very straight forward simple giveaway, like dozens of others on here. No one invested or lost anything for a chance to win. The the luck of the draw is just that.
IMHO, the amount of negative reaction is largely because you generously put up a
VERY desirable knife that almost everyone on BF wanted to win badly (including me

), so many felt more than the normal amount of desire to be the winner.
To me,that just reaffirms how generous your choice for the GAW was.
Basically on BF the norm is that it's your giveaway and you can run it any darn way you choose.
My reaction? Disappointment I didn't win, and congrats to the lucky person who did and a definite :thumbup: to you and Knives Emporium for giving me the chance.
