One term you didn't define that I didn't know either that I will define now that I've figured it out:
J-tag is apparently a type of console mod. Bannable offense to use it online.
Also avatars that have oddly colored skin or hair are a bannable offense. It doesn't by itself seem that bad to me, but I assume because you need to have modded your console to do it, so it's a symptom of a more serious offense against the ToS.
