People trolling on purpose...

Ok, Are Riot even doing anything about people trolling on purpose?, For the last 2 days people have trolled on purpose, I was at a 65% win rate now i'm at a 45% win rate, For 2 days now some of my team has fed and trolled on purpose and Riot dont even do anything about it. People dying over 10 times is badly trolling, They do it on purpose!
