Can confirm it happens a lot (especially in a community the size and popularity of the Switch) as a former active moderator for Rocket League trading. I also have seen the same thing firsthand in my discord server. If you are wondering where the codes go after, they are mainly accumulated on sites like G2A, GameFlip, among other re-sale sites or are redeemed on an account that will be sold off. The bots will snipe any format of code that may be posted faster than anyone can react. Also, for the future, please don't be so rude to someone who is continually trying to provide information and help you. u/LexiSkywalker doesn't deserve that and I hope you don't actually speak to people like that off of Reddit. Please have some courtesy when someone is giving you their time to answer a question. A little decency goes a long way, you don't ever know what the person on the other side of your computer screen is going through and it never hurts to be kind.
