You could “just” do a lot of things, but all of them start and end with requiring regular people (i.e., idiots) not to be stupid 100% of the time, which means that an eventual catastrophic failure is not only likely but outright guaranteed.
Rule 1: All post titles except for meta posts should be just plain “hmmm” and nothing else, no emotes, no capitalisation, no extending it to “hmmmm” etc.
