Hi Jimmi,
I'm guessing that Hosting companies do not generally check the content of the sites that they host. Most hosting companies however, have a Copyright and Trademark clause in their terms of service. Our own Terms of Service to our customers includes the following
Copyright and Trademarks: The client unconditionally guarantees that any elements of text, graphics, photos, designs, trademarks, or other artwork furnished to LCN for inclusion in the web site are owned, or that the proper permissions were received by the client from the rightful owner to use these elements in the web site.
Every once in a while we find someone displaying content stolen from us. The first thing I do is send them an email requesting it to be removed. If they ignore it (thieves usually do), I then find out who they host with. I then send a notice of
Digital Millennium Copyright Act notice, and INCLUDE the Hosting company. The hosting company has to act by shutting down the website if the site owner does not remove the content, otherwise they are just as responsible for the copyright violation as the site owner is.
