No, you do not have to buy any of these to create an adult site. To be honest, you do not have to get a ZingTube theme either, since there are free themes but they are not as good as the premium ones. So I recommend some paid products that are useful if you can invest some more money.

EconfirmPro is a plugin that will create an automatized webcam site and it can be used with any theme and the ZingTube one should look really great with it. You will be able to use this plugin on unlimited domains, so you can create as many sites as you want using this product.

RoboS is also a plugin which works like Econfirmpro but it comes with a theme but you can use any other theme that you want as well.

I recommend you to go to each site and check out for demos so you can see how these plugin work.

By the way, if you use any links from this site, you will get the best deal and I will receive a small commission for promoting these products on here. I use them myself and they are best I have used.

KenPlayer will work with any WordPress theme including the ZingTube. It uses a custom player, so when you embed videos from PornHub, XVideos or other tubes, your visitor will not see any annoying ads from these sites. It is a must have plugin if you want to build a tube website.

It is the first time I hear about this Ken Importer so I have never used it, therefore, I can not recommend it but XWPThemes has some great Importer plugins too. They will help you to grab thousands of videos from tubes like PornHub, RedTube and post them on your adult website.

Update: I have googled Ken Importer and it is the XWPThemes’ product so it must be good.
