To paraphrase, there's no scheme for moderation / censoring / filtering that survives contact with the Internet. It simply can't be done. People take it as a challenge, and you can't design a system that handles it while remaining useful.
If you ban words, people will introduce typos / different spelling. If you ban concepts people will change the concepts (see the "unalive" thing that's popular now). If people want to be miserable, they will be miserable. And they'll invent new words, or use euphemisms to get their point across.
