I especially dislike the ones where the site claims it needs a dozen different domains enabled to render at all.
Enable xyz.com, refresh, still blank.
See the next one down is… cdn.xyz.com great. Enable that one and refresh, still blank.
Look in the list: Fine, I’ll TEMPORARILY allow xyz.akamai.net. Nothing
Next one, sdjaildknfaskldfnasdklnhfjklnjasklfwenhf.cloudfront.net as well as cdn-sdjaildknfaskldfnasdklnhfjklnjasklfwenhf.cloudfront.net
Ah, finally, I have a page full of broken images.
At that point I just revoke permissions and write the site off as malware.
