My site does not host any images or videos or allow any type of file uploads at all. Any media that is posted on my forum is embedded from various sites like imgur, tinypic, youtube..etc. From time to time I get emails requesting that we remove images and things like that. Being that those files are not hosted on my server (US Based btw) I've been wondering why they are contacting me and not the actual host of the image. Is this something I have to comply with?
