Can I enter a giveaway for a friend?
You should only enter to win giveaways for yourself, and if you win a game, it must be activated and redeemed to the Steam account used during registration. If a friend is interesting in joining giveaways, they'll need to register for their own account.

You can get suspended or banned for that.

The only thing you can do is just not participate in GA's you don't want ͡° ͜ʖ ͡ -

Roger that and thank you

Also... You have to activate games you have won. All of them.
