It's unclear to me how that rule was originally intended to be used because most of us weren't around when it was added and it doesn't specify exactly what it covers in the rule itself.
Personally, (note the absence of yellow text) I'm not too bothered about people using just names and pictures, it's when people start importing the entire character and its backstory, or even elements of the setting they originally came from that it starts to become an issue for me.
It seems to me that this is probably how it was intended too, or surely Doc Holliday would have gotten himself banned a long time ago, along with the entire Lane Hacker faction.
