DMCA notice & takedown

Designated agent

For Digital Millennium Copyright Act ("DMCA") notices, please contact the registered agent:

DMCA Designated Agent
Email: hello@yestermark.com
Postal: as registered with the U.S. Copyright Office DMCA Designated Agent Directory

The agent is registered with the U.S. Copyright Office. Notices delivered to addresses other than those listed in the USCO directory may not satisfy the statutory requirements.

Notice requirements

A DMCA takedown notice must include all six elements specified in 17 U.S.C. §512(c)(3):

  1. A physical or electronic signature of a person authorized to act on behalf of the owner of the exclusive right that is allegedly infringed.
  2. Identification of the copyrighted work claimed to have been infringed.
  3. Identification of the material claimed to be infringing, with information reasonably sufficient to permit me to locate the material (a direct URL is best).
  4. Information reasonably sufficient to permit me to contact you — address, telephone number, and email.
  5. A statement that you have a good-faith belief that the use of the material is not authorized by the copyright owner, its agent, or the law.
  6. A statement that the information in the notification is accurate, and under penalty of perjury, that you are authorized to act on behalf of the owner of the exclusive right that is allegedly infringed.

Counter-notice

If you believe material was removed in error, you may submit a counter-notice meeting the requirements of 17 U.S.C. §512(g)(3). I will forward the counter-notice to the original complainant and may restore the material in 10–14 business days unless the complainant initiates judicial action.

Repeat-infringer policy

I terminate accounts (none exist, as Yestermark has no accounts) and remove published material from repeat infringers as appropriate.

Right of publicity

If you are depicted on Yestermark and prefer not to be, see the removal policy on the privacy page. Removal within 7 days, no questions asked.
