> Hey all - we’re looking into all ban reports to make sure everything is working consistently, as intended, and in a fair manner. If you feel you’ve been wronged by the hammer, please post time of ban, duration, and gamertag and we’ll take a look ASAP today. If you’d rather PM me that info, that’s cool, too!
As you can see, B for Bravo and his team are looking into it, and if you feel like you are being unfairly band, go to the Reddit link and do as B for Bravo suggested to get your issues fixed.
