Expired code
yes I think it was over I tried to sign up as well and try to scan barcodes but does not work
i think the giveaway was abused badly that's why they ended the giveaway?

yeah very easy to creat multiple acount creat new acount claim give away withdraw and creat acount again
better we use twitter verification (authorized app)
even then there is a way to circumnavigating it, no system is 100% secure(maybe only the vernam cipher)
these giveaway are always bad, they are abusable, and when they end everyone vanish , and go dump their miserable reward...
yes giveaway for the current system to be really safe because if it is not safe to be a lot of people who abuse
