More seriously, the initial prompt was '5ch posts your ip; 4chan should do that too', which is dumb.
And to wit, the crucial distinction here is not so much identifiers vs no identifiers, but durable/entangled identifiers, vs transient/surfacial identifiers.
Facebook would be the archetype of both durable and entangled identifiers, being literal meatspace powerwords.
Something like 5ch displaying internet protocol addresses would be durable, in that it would follow the poster across time and space, and slightly entangled, in that it would correlate to the device and or service provider they are using (which could show up in other contexts as well, cross-contaminating identity 'silos').
Something like country flags is technically both durable and entangled, but the numbers involved attenuate this somewhat.
Randomized thread IDs would be durable within the thread itself, but transient in the larger context, and also unentangled with other identities, which is what makes it a common compromise.
This is not so much a criticism of this or that concept in isolation, as much as a criticism of the general direction of travel implied by going from here to there.
