Trigger-words?

Could I get a red to explain to me how the detection for in-game chat works without being too descriptive as to give away their "secret formula" for detecting toxicity? For example, I had a really good game last night (I've been off for like six months now) and although there weren't any issues/problems among me, and my team-mates (minus one refusing to cooperate, and running in repetitively dying giving us an almost thrown game) I'd say things like: "Well shit" "Holy shit man that was nice" "Fuck" "Damn it's alright"

it was all in good spirits, and combined with a means of encouragement, or shock towards the enemy's methods which I also noted with "wp" Is there something like a counter that determines how many times a word is said, and punishes you based off that? Or does it eliminate possible toxic behavior by looking for what words are used together in a sentence? Just want an explanation without revealing anything about the super-secret system.

Edit: I was not punished for anything, just curious.
