So since two of the very few users who have been banned with SX OS only had AutoRCM, something tells me the way TX is corrupting the BCT may have been detected by Nintendo. I haven't begun the compilation of all of the ban reports yet but it might be worth uninstalling AutoRCM if you installed it via TX's method because right now, there's no other link besides the fact that those 2 users ran SX OS offline at one point (maybe v1 or v1.1 is another common thread?)
