Yes, but blame the DMCA, because this is literally what it requires content providers like Google to do:

> OSP must accommodate and not interfere with "standard technical measures." "Standard technical measures" are defined as measures that copyright owners use to identify or protect copyrighted works, that have been developed pursuant to a broad consensus of copyright owners and service providers

Basically, if somebody claiming to be a copyright owner (even if they aren't) files a claim saying they have copyright over someting (even if they don't) using "standard technical measures", Google "must accommodate and not interfere", meaning they need to take down first and ask questions later.
