hello friend,
it takes a significant number of regular reports to result in punishing actions. if your get chat restriction or something along that line, then you know that you are often getting reported
in that game you explained - I personally would have tried to get you encouraged to play again. it's a sucky situation and about one in 20 of them are actually recoverable. but it is such a hard place to be in. personally, I likely would not have reported you at all - tho some times, due to some situations which I don't feel you described here, such an afk'er is also someone I report - but as you explain it I don't think yours would've been that situation. as you described it, I wouldn't have reported you at all.
If you find yourself regularly behaving in this way, then try to slowly train yourself into the habit of keeping cool under pressure. it's a good life skill tbh.
was what you did "wrong?" friend - what is right and wrong depends on who is judging you. that is all there is. whether that person is yourself, a friend, an enemy, the police, a starving family stealing bread - all these things change the "rules" about right verse wrong. find confidence in yourself - that is what is right for you! if dancing in baron pit in unwinnable games is right for you so be it. personally, I try not to do that, but as I said. if that is what works for you, then that is what works for you.
