Ok, so let me get this correct:
The main complaint here are there are mods that individuals can install (that are against the ToS mind you) that all them to view all characters in the game as graphically nude. That is butts hanging out among other things.
There is no way to detect if someone else has this mod. This mod does not impact your interaction with the game in a direct manner. This mod is a problem because it is the thought that someone else might be seeing a character you have created in a game in their birthday suit is a problem.
Is this really where were getting at now?
Ok, the mod is probably illegal, but theres no way for SE to pragmatically enforce people to not use it. Furthermore, it only turns a fictional avatar you have made nude, it does not make you personally nude. Nor does this alter your experience with the game seeing as ONLY the person with the mod views the content, and no one else. At this point, the complaint amounts to the idea of someone possibly having seen yoru character nude and you personally find that unsettling. Thats it. To which most people have replied already : Get over it.
Simply enough, the OP is letting an idea or possibility bother them, not that the reality of hte situation. Youre character isnt actually nude. Its not showing up on your screen. Its someone using a mod that alters the game to display somethign different on their screen. You have no idea this is happening, but its the potential someone MIGHT be doing this that is bothering you. I mean, I have to ask this: Are you bothered that somewhere out there, there might be DRAWINGS of your character naked? You dont know after all. It may or may not even be on the internet, but therse a potential that someone somewhere drew your character in the buff (and probably doing scandalous things too). Does that idea not bother you?
Yes, the mod is a bit scummy in nature, in the sense do people really need to be walking around looking at peoples junk. Its kind of pathetic in that regard, but again, the issue you put forward is kind of silly. You really need to let it be and just put it out of mind.
