As we know, any free services are not done without any purpose.   There will be some kind of hidden agenda behind the free option.   The main benefit for the host to offer you free site is the advertisement income generated from such sites.  When the advertisements running on a dedicated server hosting, it will be very expensive and while it is running from a reseller or a free site, it will be much cheaper.

Adult hosting are available for cheap rates starting from $3 a month with many features that are free or unlimited.  If you want control over your content, you should look for a paid hosting.   Meanwhile, if you are going for free web site, it will not have much features.  Free adult sites offered to people who are not thinking about its commercial aspect or at the beginning stage where you are learning about the hosting services.  Why companies offering them because it will be your first towards owning a site for your own at a later stage after you experience the free services.  

Really commercial hosting services require more features and that will generate income for you.  If you are giving paid access to clients, it will be necessary to have ecommerce enabled site with multi layers security features.  You should have considered the security part for such commercial sites.  There are a lot of restrictions for the use of the contents and stricter laws will not allow you to upload whatever you need and if you invest heavily and not getting any return will make you bankrupt.   There are occasions where people thinking hosting a site is a cheaper option than a conventional business.  Purchasing a server and keeping it in any data center will not make you rich overnight.  There will be lot of hard work to be put in before you start earning.  In this scenario, it will be better to look for a competitive hosting company which offer reasonable features and without hidden charges.  A comparison study of different hosts will prove beneficial.
