agreed! , "model name" consistency would be ideal , in regards to seeing the same model on different sites so long as the photo/video work is different this will increase the models expo$ure.
nothing lasts forever , wether by the slow decay of time the model will age or his/her inabbility to change their "look" or everchanging market trends ( mild today , wild tommorrow ) will dictate "shelf-life".
