no they are not, we dont have resellers of our product. if they are buying HB Keys then they could sell them, but we're not like "heres 100 keys Mr.RandomGuy, Have fun selling them for gold!"
if you want a Legit key, just buy it from us. because here's the problem, the key is registered to HIS e-mail so if you lose it, or he decides to change this key, theres no way for us to verify that you own it, since your name isn't anywhere on it. so your out the gold or money you paid for the key. if your selling your key and you decide to scam someone and cause problems what we normally do when that happens is completely disable the key, since at that point its impossible to tell who owns it.
just avoid all the headaches and buy the key directly from us, and help support our product, our community and help us to continue to provide you with awesome support.
