It’s not that simple. A lot of the times these DMCAs are not sent to your instance email, they’re sent to your provider’s and they don’t give a fuck. They will tell you, “remove it, or we take down your whole server and all data in it”. You can send a DMCA counternotice sometimes, but eventually if you get enough bogus DMCAs, some providers just terminate your service anyway due to their hassle. It’s fucked up and the reason why lemmy.dbzer0.com had to change providers to someone more hostile to bogus-DMCAs.
