Problem with winner Humble Bundle activation

You can always claim the page yourself and then make the game as 'gifts' and give the link to the user.
But to make sure, before giving , click the link you created in the game you will give, and if it appears for you to put email and password means that is not redeemed and then you will know for sure.

OR

click redeem, and it will show a steam key since HB doesnt redeem automatically in steam anymore

He claimed the second page, but says that the link code never arrive.

Tell him to use this: https://www.humblebundle.com/resender

If he put the wrong e-mail, then it's his fault and... I don't know, you should tell support about it

Currently when dealing with bundle keys, I just get the key myself, instead of expecting a giveaway winner to jump through bundle hoops, enter email here, click there, etc. to finally get their Steam key. :)

According to other people, you can contact Humble Bundle support, and tell them you're having problems with a key. Apparently, they can invalidate that key and provide a new one. So if someone's trying to scam you, the old key they might have copied won't work. And if they already traded it away, the game will be removed from whatever account used it. Not your problem. :)

There was a forum thread somewhere with a possible caveat, however. Mentioning Steamgifts caused the Humble Bundle support to stop helping because we're key resellers or something? Don't remember the details, unfortunately...

all my HB gift were also "gone" before (even though i NEVER give it away)
they said it was hacked (for real??)
but fortunately it's all been reset now and already redeem it all

the thing is, my unused key but already opened one still safe
maybe it's the same problem?

I just dispense the key and give that to them directly... Too much hassle to have people use bundle links. They might not even have an account for that bundle site.

This is as fishy as it gets. Some winners give won games to friends or trade them when they say keys are dupes or whatever. You provided two keys, now it's his turn to give evidence.
Contact support.

cant help you on the first case.

but i've had similar problem with your second.

traded a HB link, tested as unclaimed. he claimed it and later claim that the email to redeem the code never arrived. After a lengthy conversation trying to figure it out, i finally was able to get the email address he said he used to claim the hb link.

With that information, i sent an email to hb support asking them if this particular hb link was indeed claimed to that email address and whether or not the game has been activated.

Hb replied that the hb link might have been claimed with a typo, thus they said they reset the link and gave me a new link. I gave the new link to the person i traded with, and had no problem afterwards.

Interesting to note is that HB does not confirm/reveal the actual email address used to claim the 1st failed page. They only straightforward stated that it might have been claimed to a mistyped address, nor did they reveal whether or not the game has been activated.

tldr, get the email address the winner used to claim ur hb link, check with ur hb support and their reply should indicate if there was any shenanigan involved.

also, if you need, you can claim the humble bundle gift back if you contact HB support.
