I have a file with all unused keys I got from bundles, is there a way to check if the keys are still valid?
I had it one time that a key was invalid.
I would like to give away most of the games, but don't want to create a giveaway for a invalid key

Edit: my search- fu is really bad D:

Thanks for the links!

Nope no way to see if they still work without activating them.

There's no way to check the key without activation, because you could try to determine the right ones and then for example sell them. Kinda like keygens. But some bundle sites allow you to set the status (activated/not activated) from your profile, to make it easier to determine if it's still valid.
