Well this happened to me today. I check my teamates before every game. After many games were people just feed the whole game I can't take it anymore and I check everyone, if I see more than 1 player being bad with many loses in a row or a lot of feed I disconnect the game during the loading screen. Did it 3 times in a row and went from a 20min ban to a 24h ban... well that escalated quickly, meh no dota for 1 day for me but I have to wonder Valve's policy if you disconnect during the queu you get 5min, 20min and finally 24h ban in that order. If you abandon during the games you go to low priority and especially the first time you abandon you don't lose anything except taking a loss, seems a bit unfair to me, what do you think?
