Can't speak to AWS, but I used a dedicated box at another US-based provider as a seedbox for nearly two decades. When they received a DMCA complaint they didn't provide our information and generally just didn't seem to care as long as we provided the bare minimum of ass-covering for them. We'd get a ticket opened against our account with a copy of the notice, reply "We've identified one of our users operating in violation of our TOS and have banned the offending user. All copyrighted materials referenced have been deleted." and they'd close the ticket every time. I imagine if this was more than a once-every-three-to-six-months kinda thing the support burden would have had them drop us as a customer, but at no point did they share our information or did any rights-holder take it further.
