I've also seen several very respectable models who were very encouraging and gave their fellow models compliments/encouraging words. However, in each situation, no matter how good their intentions, I always got this sense in the back of my mind like, 'this is just shameless self promotion.' Which is all the more reason why I think it's better if models sign up for separate, 'incognito' premium accounts solely for the purpose of them admiring their fellow cam crushes. Key word: incognito. There's really no reason why anyone should know who that other model is, unless she is trying to get her name out there purposely.
I think the worst thing I saw was a particular model (whom I'd always viewed as a nice girl) come into a fellow asian model's room ad say '________, I mean no disrespect, you're really pretty and all, but I don't get why you don't just show us your ta tas since you already have them in a hand bra.'
Needless to say, it resulted in a ww3'esque tirade where the model chewed her out relentlessly, saying it's her room and her rules, and she should know better than to come in to another models room and dictate what she should or should not do. She was subsequently banned, and from that point on, I just never had a particular liking to seeing models in other models rooms.
