Re: Starting from scratch
You don't need to start all over and make a new name - because your fans already know your previous name as it is keep it simple and start from what you have now.
You don't need to go back and re-edit videos its just giving you more work that you don't need to put your energy when you should be using that energy to move forward with what you want to have next.
As for cam sites wanting exclusive yes they say they do but they don't always get them, like for example split camming is not following the exclusive rule, if your creating a website on southern-charms they want exclusive content and they do enforce it. Cam sites not really. You can have a set of photos that you use everywhere as your brand yourself.
