In most cases, your webhosting company is not responsible for your website. They are responsible for providing the server and connection to the Internet. So here’s an elementary break down for you. We’ll compare it to a store in a shopping center.
This is all the stuff you PUT IN YOUR STORE underneath your sign. This would be your vibrators, butt plugs, anal lube and so forth. YOU decide which products are in your store and how you sell them.
This is the most simple of all. They are the building. The brick and mortar. The glass front. They neither determine what butt plugs you put in the store nor do they determine the size. They simply provide, at a cost, the place to DISPLAY your butt plugs. Nothing more.
Does it get any more simple than that?
