Like I said, no one so far has been banned yet for using AutoRCM alone. That may or may not change in the future.
Yes, I think that is the only "risk" thing that I do. My sys is totally clean. But, as a beginner on hacks, there's one thing that buggles me with autorcm leaving or not leaving traces.
Like, let's assume that nintendo launches a new OFW update that bans people who uses AUTORCM, and before i update on my sysNAND, i turn off autoRCM. The traces will be enough to cause ban or turning it off before won't? That's my point, are the vestiges all that visible?
