"Of course they do! The Pro is on there, isn't he?"
Not everyone has seen the unedited video, so i suggest you watch it.
The banned user, iTzLuPo, says he glitches and mods in his profile biography. The Pro banned him for modding, which is listed as a bannable offense by Microsoft.
If you are interested in seeing the video, I strongly suggest watching the unedited version, which will show the behaviour which caused the user to be banned.
