Hello everyone,
Yes, the Bhangra Boogie Emote is forbidden to sell on the Gameflip marketplace since it is a free promotional offer by OnePlus and only to be redeemed by owners of specific OnePlus devices.
So we are handing out warnings at first, but if we see that this item is still being sold, further measures will be taken.
Also, here is an explanation on the OnePlus website as to who is eligible to redeem the code.
God Speed!
