We have a number of partners that allow us to provide our free hosting, in return for advertisment of their paid services.
These advertisements are only placed on our website in the form of non-intrusive banners and third-party upgrade links. We do not currently advertise directly within cPanel, and we have no plans to advertise on clients websites.
However, clients are required to link back to our website and if they provide a commercial service, they are expected to upgrade to a paid package.
In addition to these advertisements, most customers don't fully utilise the space provided to them, and although we can fully provision space for all customers, it's unlikely to occur.
Therefore, we can safely oversell our free services without effecting the performance of our services.
