Yes, sorry if I wasn't clear. These "fake DMCA submissions" would be labelled under "muddying the waters". Fake submissions from fake gmail accounts set up in real cyber cafes or using very real botnets.
Content from site A and copied onto sites B thru Z. DMCA submissions from site G accusing site D, from site N accusing site K, from site W accusing site G, sites H, Y and T accusing sites R, V and A. Site P accusing itself. Round and round we go. Endless junk that all has to be gone through.
Imagine a billion submissions claiming 5 billion URLs are copies of 5 billion others. Who gets to decide? Who gets to bang their head against a brick wall first?
