DNFTT worked in an older era.

It doesnt work now, and with the diversification and use of the net by vulnerable groups.

Having a users on a generalist forum suddenly exposed to flashing lights to induce a seizure, or ambushed by images of dead people, or being attacked for being a woman or a minority group?

Yeah you cannot expect people to shrug that off, without also expecting a large mass of humanity to be essentially living without a normal emotional response.
