"I will add the winner on Steam"

Does it matter? Honestly? o_O

Some people like adding the winners of their giveaways so they can speak to them and give them their games directly, some people don't...

I do most of the time when it's a Steam gift, simply because I like to trade it directly so that there's a record of it right on Steam, sometimes I even do it when I'm giving away a key.

But honestly, why does it really matter to you?

Are you winning a lot of giveaways where the winners add you and you're not able to delete them right afterwards?

I always make a point to tell people to not worry about removing me, it won't bother me at all.

I think you're missing one thing. They usually don't want to become your Steam friends, it's just only for gift delivery. I prefer adding winners too, it's faster than mail.

Well whem I say it, it's like how Crocross explained. It's to let people know I'll be adding them so they can maybe expect a friend request if they won. I'd wager a lot of people didn't read where I said that or forgot, but maybe it will give someone somewhere a clue as to why I was adding them.

I don't care if they remove me straight after.
