Negative Attitude Correlation with 4v5s, afks, dc's, etc.?

I won't lie I've gotten the occasional verbal abuse report warning a couple times since I started playing since season 4.

One thing I've noticed though is that every time I get one it has correlated with a leaver afk/dc on my team. I'm sorry if I'm not all sunshine and roses in chat when my team is losing because of some server bullshit or someone decided he didn't like his lane match up and left.

Now I know I should just shut up in these situations and avoid chatting when I am in a bad mood but when the enemy starts boasting or spamming taunt or laugh while they have us penned in base I am gonna strike back in game and verbally.

Whats worse is that it was my own team member who did the reporting the most recent time. I don't get it, I never bothered or insulted him, I was an awesome support that game (my adc even said so before the server failed her) and I kept trying and did not give up or vote to surrender despite my saltiness.

However once I told the enemy team what I thought of their bm moves and arrogance everyone turned on me calling unskilled salty and report the Nami. Well gg to that.

What I wondering is how often are reports of bad attitude/verbal abuse associated with trolls,afks,4v5s etc? And if there is a strong relation maybe we should focus on having no 4v5s or afks before getting people reported because they have to lose a game because of something outside of their control?
