Im hosting noobs games, i lost more games than i win, that is ok, what is not ok, that someone who dont have a brain, and join pro games before, then got a idea to join noob game and ruin it, no wonder, he got 10-0 or 15-2 by 30m, game ruined, no fun, 26-10 or 30-5 for other team, what can i do in this situation ? I check scores in begining of games, but i cannot look on website for everyone if he have this score by joining noob games or pro games, and then i think there some rules about this: like other team can leave if they seen by mid game and check it, that he is indeed joining 95% of pro games, or that we can votekick and if other team dont wannt we can free leave or maybe report him and ban him for ruining games, cause having 0-15 and having 15-0 is same result, game is ruined both ways.
Well stats can help. You can tell noobs from pros by checking the cs for example. A noob will usually have 40-50 creeps killed, low denies etc. Also, pros usually have a more or less balanced k/d and a high amount of assists, while noobs, or wannabe pros tend to ks all the time and have high kills, but almost no assists..
I would rage quit, bash my desk, uninstall dota and start playing tetris.
this says everything
