I work at a group home with mentally disabled individuals. One of my guys loves halo and plays even though he almost always gets no kills. I got banned when I played with my profile and him signed in as a guest. I already got banned once when he was signed in on his profile and I get that, it looks like I was credit boosting his account. This time I thought that having him signed in as a guest would work because there was no boosting to be had, but I still got banned!!! They really need to fix this. It makes me not want to play halo, and it is very frustrating!!
