Title 17 of the United States Code was amended by the DMCA to extend the reach of copyright while limiting the liability of on-line service providers for copyright infringement by their users.
It was signed into law by President Bill Clinton on October 28, 1998 after passage by a unanimous vote in the United States Senate on October 12, 1998.
Many of these types of predators are abusive both emotionally and physically.
However, if such a demand is made on the basis of copyright breaches, you may submit a similar take-down, but based on copyrighted material such as photos, images, quotations, or other copyrighted material owned by you, or another party willing to support you in your take-down efforts.
If the victim is in a relationship, they will threaten to send the photos to their partner.
The abuser may threaten to discredit or embarrass the victim by sending the photos to the victim’s employers or clients.
A word of warning though; if you direct such a take-down demand to websites with low value speech and poor social responsibility records, then you are effectively “telegraphing your punches”.
In such instances, stealth might be your best friend, as such, it might be tactically and strategically prudent to limit your DMCA takedown demand to the search engines only.
