A user has been yelled at by Flow for basically using the word "Thanks" (MatmaRex explained to me that it's because the word "has 1 three-letter consonant cluster, which is more than or equal to the number of words in the message (also 1)".
The explanation of what was wrong with the message could also maybe be improved, but more importantly, it shouldn't look like one committed a crime (in case you're able to actually make it distinguish between a simple warning and an error message).
