Short answer: Yes. Details: The longer answer is that, yes, there is one site which is known to be bitchy about models appearing on other sites. BlueBlood.com is not one of the sites they are bitchy about in that way. Some of the girls with the most sets on that site modeled for Blue Blood first and some modeled for Blue Blood second and continue to have sets posting to both BlueBlood.com and that other site. So there is no legal problem. However, if you seem like someone who frequently works with bad people, this may turn us off because you are judged by the company you keep.
