Not sure what the official rules say about this, but I agree with you 100%. This "I will add you to friends or no game" is complete bullshit. Don't add me, send it via email like SteamGifts wants you too. Not only it's build into the SG page, but it adds an extra layer of security, giving you an email proof if the correct key was sent or not.

The rules for how the person wants to give the code to the winner is what ever way they want to do it.

I will not send stuff by e-mail anymore because there has been a few cases where It took a while to finally get the person to hit the received button.

If you don't like that they will not send via e-mail, well thats just too bad isn't it. There is no rule that they have to send it by e-mail, there is no rule that they have to send it via friends chat.

Now I do agree that if someone is not on when the giveaway ends they will not get the code is silly after all not everyone can be on at all hours of the day. People need to sleep, people need to go to the bathroom, people need to go to work and/or school. The rules of the site says they have up to 7 days before a reroll can be asked for for this reason.

My recent experience has been people not ever checking their email and I had to get a hold of them on steam. I will make every possible effort to contact a winner. I just don't want to send a code to someone who never sees it.
