Pretty awful, actually. I've had a few dozen Steam game keys lying around since I stopped trading a while back, finally decided to get rid of them via a batch of SteamGifts giveaways. Turns out I got sold a bunch of used keys. Due to regional pricing locks, at least half the winners can't be given the game by my just buying it and gifting it through Steam. So now they got stiffed out of their winnings, and I'll be getting flagged as not sending gifts, temporarily suspended from SG, and probably kicked out of all the mostly private giveaway groups I'm in. Yay.
