Im just playing a ranked game i need a win for silver 5 and i have a ghost cleanse nunu feeding and running everywhere doing nothing i have a kassadin jungle and a lee sin support and if i dodge i get a lost game and maybe i get my account banned
Dodging games will only result in a ban under extreme circumstances. if ever, never heard of being banned for dodging
Trolling in games is punishable you can report them and hope they will get punished. On the other hand system sucks its effectivness is w/e and some people posted they inted ( not trolled, and trolling is harder to detect ) for 30 games before they were banned....
Sadly the only advice is just chill and treat the game as practice its most likely lost but at least you can have some fun. Or dodge and most likely you will get 1 free win in next series.
