With CB support's response time being so delayed, there are things that you can do on your own (if you want) to file some claims yourself as well. At the bottom of most of the sites that post stolen content you will fine either a DMCA link or a contact us link. Inside of those pages you will either find an email address that you can reach out to with the request or a copyright takedown form built into the site itself. If you are going to email a website to request that content be removed, below is the DMCA letter that I have been using for years that has helped me to get thousands of stolen items removed.
Dear Sir or Madam,
I am writing you on behalf of the copyright owner for certain information that appears on your site/servers without authorization.
This infringing content can be found on the following URLS:

This information was taken from the following website:
[Your Website]
Please accept this communication and my statement, on behalf of the copyright owner, that I have a good-faith belief that the use of the above-described copyrighted materials is not authorized by the copyright owner, its agent, or the law. The information in this notification is accurate, and I swear, under penalty of perjury, that I am authorized to act on behalf of the owner of an exclusive right that is infringed. Should you require additional information please feel free to contact me by response to this email.
Please reply to me to confirm that all of the infringing content has been removed. Please ensure that all repeat infringers are being terminated, per the requirements of 17 U.S.C. § 512(i).
Thank you for your attention to this matter and your anticipated cooperation.
By typing "s/" followed by my name below, I hereby adopt that electronic signature as my own, pursuant to 15 U.S.C. § 7001 (the "ESIGN Act"), and affirmatively consent to its use as such.
With much appreciation,
s/[Cam Name]
Just remember, if you are requesting a video be removed, there is no need to use your real name. Most sites will remove the content without this information, and if they do request it, know that they will likely refuse to remove the content anyway.
Also note that DMCA law states that any information given in the process of filing a takedown request may be sent to the person that uploaded the stolen content (which is why you don't want to use your real information).
Hope this helps!
