It is good to know that you have verified one of those links. Did you report that or any of the others?
What has your experience been like trying to remove infringing content from that site other than you distributing links to said content on other websites? Your confidence that this is so clear-cut flagrant disregard for the law indicates that you must have engaged with them extensively in some way other than sharing these files with strangers online.
I think you're missing their point. Even if the poster does report it, it doesn't really change the fact that the Internet Archive is basically the best place to pirate media, and as I keep saying, if I know about it, their staff certainly does too, they're not idiots.
