So, you have a virtual private server for your website that is free to view for your general audience like children, teenagers, and adults alike,–all without sexualized content. However; you are about to create the anotherwebsite that is going to be suitable for adults only, but you don’t want to get the burden of having to be cluttered with 2 sites on one server via 2 domains.
You need to set up a new domain that is suitable for a website that is suitable for adults over 21 years of age. However; pornography is out of this question!
