Game is unplayable after new role bans for roaming supports etc

[fuckvalve69]

I play alot of roaming support with unusual support heros like sven invoker slark wk kunka lc.
The new report system has made the game unplayable for me. Even if I stick in lane and play position 5 and win the game for my team. Since the reports come in at the selection time and Im hit with atleast one idiot reporting me. I got 3 day bans on my 2 accounts from playing about 2-3 games on each. This is absurd and will kill dota for position 4 players. I dont like to play core so my only choice will be to leave dota if this is not fixed.
