I very much doubt that the AB team have paid someone to think up every 'naughty' word that ought to be blocked.
Instead, they'll have downloaded a standard list of 'offensive words' from somewhere, and have configured their software to eradicate all such terms. The result of doing so is probably that many terms which are not recognised as readily offensive in the UK (but which are considered so in the the USA , where the list of terms came from) will be blanked out.
