How long do people have to activate a gift before you should report them?

O really?

lol what? What in "You must redeem the game on the account you entered with, and may not trade it to others." you don't understand?

You MUST activate your gift as soon as possible.

Bollocks. They have to activate it. They can't regift or trade it, and to leave it sitting in inventory is almost as bad.

Wrong. They have to activate it. "Winnings must be redeemed on the winning account."
Quoted from the FAQ.

point being, unless their inventory is public and you can SEE they kept it in their inventory because it looks better there than in their library, we won't know IF they traded it. They only way to be certain is if it is redeemed.

Also, they could theoretically still enter the same games giveaway again.
I am asking because i found no acute timing in the FAQ, but yep, i am pretty certain they HAVE to activate it. Look into report users.
It says "Trading OR Not activating won Gift"...
