I'm not sure (not a lawyer). In theory, both request should be squashed, and I think there's a serious penalty for knowingly issuing a bullshit request, but i've never heard of the big guys being sanctioned, perhaps they lean on the excuse that their automated tools generate false positives. So you need to put up the content, and then point crappy automated tools at the big boys, maybe. I'm not gonna do it, but if someone who knew what they were doing managed to generate a ton of takedowns at the large providers, in a legally safe manner, it might at least prove a point and generate some press.
