The 'Tattooed Woman' is a legendary, classic element - almost an archetype - of eroticism. Long before the Internet. She's a symbol of freedom and self-definition in a world full of uniformity and aesthetical narrowness. When sites restrict themselves by refraining to present tattoos on bodies, it is due to an all too opportunistic concession to a group of fans, which is becoming even smaller and bored from the same-old, same-old of teenage and slender body types. They've been there, done that for more than 20 years.
Wiping out tattoos from beautiful women's bodies is the pinnacle of hypocrisy. The message is: "We not only restrict ourselves, we also 'invent', we 'design' a model in a new way. We present you models, who just do NOT exist in the way we present them." The consequence is obvious: when technology gets better, they will not only photoshop models, they will replace them by virtual graphics. They already do! I can give you names of hundreds of models who are very famous, but their bodies are completely unknown to us. Their body shapes get idealized, their own body art is completely gone. This is NOT the freedom of art which led us to Erotic Art, to sites presenting the exciting richness of Nude Art in particular.
When the only solution for a model is, to present her body with Selfies on seemingly 'independent' model accounts, when Nude Art connoisseurs start to pass on quality in favor of getting the 'real deal' of a model's self-expression, but without the expertise of brilliant photography... THEN the methodical self-destruction of the whole industry of Erotic Art in the Internet started to become VERY successful!
