I found out something about Indie Gala gift redeeming process which you may already know, but I want to share it just in case.

When you want to give someone a key from your Indie Gala account, there are two options: reveal the key itself like you would do to redeem it yourself or create gift link which doesn't show you the key, only to the receiver. As obvious choice for gifting/giving an option number 2 might seem, there is one detail that is not so much. Namely, when the recipient opens up said link, a valid e-mail has to be provided in order to receive the key, much like what we've seen with Humble Bundle gifts, but unlike that case, here the gifter can see in the account section from which e-mail was particular game claimed from. So, if you don't want to reveal your e-mail address, ask the sender to deliver you unwrapped key directly.

Hope this'll be useful to someone.

Earlier humble bundle used to show steam accounts to which keys were redeemed (it happened if you redeem a humble gift link and instead of claiming it you send that key to another person once it get activated you could claim said yourself and see who redeemed that key).
It happened because they didn't use to provide key at that time and instead a steam account was linked to the key.

Thanks for sort though.

didn't know that np
