On the list of "things that get me to think of alternatives" this behavior is pretty high up. It's aggravating to be told what I am allowed to type. I do not want to type manually just to get around a correctness filter.

I could understand if they just wanted to make sure no accidental swipes resulted in shit, piss, fuck, cunt, cocksucker, motherfucker, or tits. That is defensible (though I'd want a toggle to turn it off and accept the risk). But they go so much farther, into phrases that some genius there decided I should be offended to type. That's too much.
