lol we and everyone knows that disclaimer is pure bullshit If you have warez on your website is your duty to delete them. Just that fact that your are "facilitating" an area for warez distribution is more then enough and no matter what you put will make you any safer.

Get a DMCA Page with the correct laws for your country and the country the site is hosted on, and an easy way for them to contact you. That way they will just ask you to remove stuff instead of going to your host.
