>The first line of recourse is counter-notification, which reinstates the content.
Sec. 512(g)(2)(B): "upon receipt of a counter notification described in paragraph (3), promptly provides the person who provided the notification under subsection (c)(1)(C) with a copy of the counter notification, and informs that person that it will replace the removed material or cease disabling access to it in 10 business days"
What can the victim of the fraudulent takedown do for those 10 days? Maybe go to court (I have no idea), but if so that certainly sounds like "long expensive legal process" to me, and if not then it's even worse because there is just no recourse at all.
