DMCA@camwhores.tv
When it comes to actual deletion of the video, you do not personally have control over that anyway. It will be up to an admin to remove or unlink the content.
However, DMCA is US Copyright Law. It is only enforceable when it pertains to websites hosted in the US. While many other countries will comply with a takedown request, they are not forced to do so. camwhores.tv is not hosted in the US. Regardless of where it is currently hosted, in the past it has been hosted in Iceland, The Netherlands, Russia and other countries that are not particularly willing to spend their time chasing down such things.

Is DMCA for the USA only?
While the DMCA is part of USA Copyright Law. The DMCA Takedown process described within the law is widely used throughout the world. Most countries accept the standard DMCA Takedown Notice form and process. Although the DMCA Takedown is part of US Copyright law, a DMCA Takedown Notice is often used and accepted throughout the world and not exclusive to the United States. However, many countries have their own copyright laws specifically related to the removal of content from internet service providers and site owners within their borders. Which service providers do and do not accept the standard DMCA takedown notice form and process is dynamic and constantly changing.
