I have bought several keys from woot and have had no issues activating. The deal is quite frequent, i think i've bought around 4 or 5 over the past few months for friends/family. The key comes as a tracking number which feels odd, but like I said, no issues.
As per the thread title, near every response to your question has been answered with either AMD Ryzen 2700x or a ThreadRipper variant. I think you probably should close your thread as you don't like answers given. Just my two cents.
