Sir.Braka: should be,you bought them,who activates them is no business of them i guess,or other Sellers for that matter.
eleve: I just looked at the Humble bundles and they redeem the keys for MY Steam acct. There is no way to use that key as a gift; it even says so in the small print at the bottom of the activation page. This was what brought up the question for me because downloading and passing a game on to someone else doesn't transfer it at the store where I bought it. So, as far as Humble is concerned, 2 people end up with my copy even if I never touch that game.
edit to add:
or am I seeing this wrong?
look,even if the page is not "claimed" your puchae you can still give that "adress" to page to whoever you wnat its not "tied" to yoyr steama ccount whoever wnat to activate on steam can do so on that page,some unless the Seller is promting to connet to your steam account and you must do so from your purchase page , for exaple no key,just actiavtetion ,but humbles claim page" dint have that no that i ever seen
edit lol i cant spell toningt...its all fogggy..andblurry
