I doubt people that are already systematically stealing material can't hide, or forge arbitrary identities.
Naming and shaming doesn't work for such attack vectors, it's a social strategy for people that have a real identity established and are making money out of that, not for ephemeral identities of such scammers.
There's a distinction to make: they are not only being "protective" of their IP, they are also very actively attacking the people that doesn't know legalese. Similar story with Oracle, if you need some reference to solidify what they're constantly pulling.
It's just that people have taken different routes historically.
