You could build something that prevents people from being offended. Let them answer simple questions like are you offenden by . If they answer yes, no allowed to join.
That would still require posts or communities to reliably label their contents correctly right?
Maybe the only solution is sulfuric acid. (or alcohol)
I strongly belief that if we all strived to get the maximum amount of alcohol into our bellies instead of the maximum amount of money into our accounts society would be much nicer.
You have written tests for your code and now feel safe because your code is tested. But test quality is really hard to measure. The idea seems to be to introduce “vulnerabilities” (whatever that means…) and see if your tests catch them. If they do that’s supposed to show that the tests are good and vice versa.
