Temporary ban

So uhh, not really a complaint here, just a question wondering how it works... I just flamed a bit in a game (where the enemies clearly did enjoy it cause they joined in.... either way) and it was the only instance where I was reported, cause that's the only game that showed up in the chat logs, so I'm just wondering, does 5 instant reports from one game give you a ban, and also does the ban lengths vary depending on how many reports or how many games this has spanned over?
