I wonder if just injecting a typo into each banned word when its used will be enough to bypass the keyword search for auto-banning.

Or take a page from IDN homograph attacks in phishing/whatever and replace certain 'a', 'e', 'o' letters with their unicode equivalent that's not English.

Which will have side effects affecting other realms (search and indexing etc.).

And besides, when a regime asks e.g to "prosecute all intellectuals - wearing glasses will be a sufficient criterion to identify them" workarounds are not the point.
