I know this from experience
long story short, i made an irl friend(?) after this game
https://www.dotabuff.com/matches/3764553952
I'm treant, he's sf, we played on the same internet cafe and were basically the high mmr-s there
my queue time is 3 mins, i had 15+ commends, 0 reports, 0 abandons and i was mad getting toxic players but i played from 12midnight to 3 am during that time
his queue time was half hour to an hour and he was 6 month ban imminent for a long time before, u can see the account has been 6 month banned now.
I know his new acc
he's still toxic but way less than he was before
we talk everyday now
