Why go with anything other than blacklist since people know what it means. It's the peak irony that we're discussing Google banning profanities here and arguing about your puritanical society.
Unfortunately it seems the less religious Americans think it's only the dumb hypocrite Christians acting like that.
We, Silicon Valley liberals, surely don't have anything to do with that culture!
It rolls off the tongue better than blacklist, since a hard consonant in the middle of the word is slightly harder to enunciate than one starting the word.
But, should you instead mean "I don't like it so I'll ridicule it," well, I can't please everybody. Sorry.
And blacklist doesn't actually mean anything without the context of an archaic idiom; it was a large barrier for me when I was younger, until I eventually learnt what the word means. You can go with “blocklist”, if you'd rather; that's similarly meaningful and sounds similar.
