Junk Bids on Trades!

I am so tired of people bidding junk on expensive items.
It is such a waste of time. I am not going to accept and I will block the person that bids junk. My block list serves as a resource for future bidding also. Most likely if I have blocked them, I will never accept another bid on any item.
So they may want to think twice before making a junk bid. I may have an item they really want at a good price at some time.
