"Nude" and "non-nude" are not clinical categories. It is a spectrum. It goes from wearing a burqa to showing close ups of your buttcrack. I understand that getting questions can be frustrating but consider that we are all in different spots along a spectrum, and not many of us are on the extremes.
Consider how a true non-nude camgirl, the kind that doesn't even take her top off or wear cleavage (like Iris or Mara or Piper) feels towards someone who does implicit nudity and wear nothing but pasties and a thong on public chat. The pasties model feels that she is the true non-nude, but for one of the more modest ones, she would be the one misusing the word!
Then there are other things to take into account. There are true non-nudes who in spite of never taking so much as their top off, do beautiful agony shows or cum shows in public by rubbing themselves through their clothes. They can certainly call themselves "non-nude" and would be more right about it than the tame girl with the occasional slip. But the actions in her room are more similar to a hardcore model while the slip girl is closer to the non-nudes. See what I mean?
The way I see it, "non-nude" is not a term that is used in a strict way. It is used by models who feel their rooms and their vibes are sexually different from the vibes of most rooms. Some of these girls truly are non-nude. Others do nudity implicitly by covering certain parts with sheets, hands, or other objects, and there are also models who call themselves nude even though they do topless in public because the focus of their cam is more artistic than sexual and they do not do cum shows live. So "non-nude" really means "tame", "mild", "tease" or "artistic".
Personally I think we can divide this issue into 2 axis: sexuality and nudity. Explained on the chart I just made and posted below.
On the upper right quadrant we have models who are 100% non-nude, and who also do not use their sexuality in any way. Their rooms are about friendship, games, and chatter. Some of them even rule out romance altogether and talk freely about their SOs. Iris, Mara, and Piper are good examples.
On the lower right corner there are models who are completely clothed and yet do cum shows. Like Amelia. The last time I perved on her was over a year ago so things might have changed, but from my recollection that is how she ran her room. Dakota is close to her. She is 100% non-nude in public chat, but will talk dirty all night so she uses her sexuality heavily. In group she does slips, rubs, and BJs, but no cum shows and doesnt even take her bra off.
On the upper left corner there should be a model that does nudity freely but doesn't do anything sexual (no cum shows, no g/g shows, nothing of the sort) I dont know anyone like this because they don't interest me much, most of my time is spent on non-nude rooms. But if someone knows a model like this feel free to tell.
On the lower left corner we have models who use both nudity and sexuality with few limits. They do public cum shows, anal, sex machines, g/g, some have b/g videos for sale, etc. Most models fall on that quadrant.
Then there are a bunch of models in between who represent some qualities and yet they dont have others. It is very hard to place some of these girls on the chart. I did my best, but I probably made mistakes, feel free to point them out. Also if I used your name and you dislike being in the chart let me know and I will take the image down, I dont want to make anyone feel uncomfortable, but figured that using examples would be best to illustrate my point. It is also great publicity should someone be looking for more non-nudes to follow, etc. Some model's names have changed, I used the one that stuck with me (such as mini, she goes by "serafina" now, but I loved her other name more)
Now... is it fair to call Dakota non-nude when she does sloppy BJs in group and not call Tesla non-nude because she ocassionally does a topless show in public or sells nude videos? If you are using "non-nude" in a strict sense, then yeah, Dakota is a non-nude while Tesla is not. But in reality Tesla's room is much more tame than Dakota's. So when a girl calls herself "non-nude" what she is talking about is "I am not the regular model, I am different" "I am artistic" or "I am a teaser" or "I dont do hardcore".
If we used "non-nude" strictly then we would have to use it to describe ONLY the girls who TRULY are non-nude, who don't even get naked "implicitly" such as Iris. And it would be a pointless word because it would describe exactly the 0.1% of models. It would be a useless term. We all use this term because it caught on.
If it bothers you to clarify, don't do it! Why don't you tell them something mysterious? Tell them "stay here and find out" or "what happens in Vegas stays in Vegas". They will bother you less if you stop replying to their questions directly, and it is more fun both for you and your members.
