Re activating expired minecon codes

Hello,
So there is an exploit where someone can re activate Unredeemed minecon codes previously expired by Mojang. All you need to do is go into base64 and take the number and letter token and decode it in UTF-8. If you don’t believe me feel free to give me an unredeemed code and I’ll show you. You also much change the link to a my.minecraft format like so https://my.minecraft.net/en-us/profile/redeemCape/
So this will let you get links like this. Able to redeem codes

That one was used already but it’s how they keep activating them in today’s date. I am only telling you this because I have already been scammed over 600 dollars and so have others for those capes. Please put a stop to it so nobody will redeem another minecon and stop this market that’s hurting so many.
