meh, whoever claimed it, didnt evem reply to the tweet. another coming later today!
to avoid this kind of issues you can follow my idea.
instead of posting public, you can send coupon through message to your followers randomly. so people can follow you & claim their free ghs.
but that would a) make me decide who wins it. b) force me to use their api to send to a random follower
EDIT: and also, how would you ever know, that i am in fact giving out codes, if i only send them via direct messages, A) the public will never know B) if you dont win, how do you know i even sent one out to anyone .
