Giving away Claimed (but not redeemed) Humble Bundle keys

Simply write in the description "Please allow me to delete this giveaway if the key is not working"

Thank you for answers, the games are from Humble Bundle Choice and selected as Claimed, not Gifted, therefore the keys are not redeemed, legit and working keys, but it seems it is forbidden to give away those keys. I just want to be sure and follow the rules.

Don't use gift links and NEVER mention steamgifts to humble support or they will call you a trader and ban your account.
They can and DO track which email addresses redeem humble gift links and, if you spread these over too big of a pool, call you a trader (see above).

Use the steam codes if you choose to give humble games away.

Thank you for your answers.
So it is the other way around?

This comes from FAQ page:
"Is it possible to send a Steam, or Humble Bundle gift link to my winner through the site?
Yes, you can follow the instructions for using a Steam key as described above, but enter a gift link rather than a Steam key. The gift link must be entered in one of the below formats.

https://store.steampowered.com/account/ackgift/XXX
https://www.humblebundle.com/gift?key=XXX
https://www.humblebundle.com/?gift=XXX"

I just want to give away the games from Humble Bundle monthly Choice I am not interested in, this could be 3 or 4 every month.

If you reveal the key and then send that key to someone else, I don't think Humble knows where the key was activated. For all they know, you activated all the keys on your own account. If you create a bunch of gift links and send them to other people, that is done through their site. They know you are buying bundles and passing the keys around to a lot of different people. When they see a bunch of gift links being used, they might think you are reselling or trading the game and I don't think they like either of those.

You have been on this site for 5 years and haven't noticed something like half of the keys here came from humble?

Thank you for all answers
I know what to do now
Merry Christmas
