I'm assuming the words "black people" and "stupid" are  a trigger. I'm not digging through the code. Let's find out:

I know some black people. They're fine, but my dog is black and she's stupid.  

 If that's for real how this bot works, it's *beyond* stupid. Typical socialist, though. 

 That didn't do it. Has to just be the phrase "black people are too stupid" without the context. 

We'll find out. 

 Hate speech is only a problem if it's in the first few layers of replies. Or if it doesn't repeat too often.  

 xD It will magnanimously let you get away with the occasional third-layer slur. 

 There always seems to be a rainbow associated with intolerant censorship types and bots.
