In my post I just want to show that not every copper member pays for membership just to make bounty, but I still think that this is the main reason for majority of them.
I think that most of them pay for this because they want to post ANN or BOUNTY thread with pictures.
But as this thread shows Copper Member number is growing more rapidly after the the new rank requirement this means more Copper members are bounty hunters.
I also think that many of the bounty hunters have main account also in this forum that is nice and tidy and cant be related to spamming
