I know its unrealistic, but can we do something about the troll picks in ranked?

I mean, I not one to judge, I've played plenty of weird picks. But sometimes that shit is better of in normal's, not in my ranked games. Some, oddly work, adc's in the jg. Others are like there is no way that can work. Or that might work, if you build right, but then you get an AD malz. And no surprise, most of his jg in gone, he doesn't hurt. Point is people intent choose picks they aren't comfortable with (ie. the malz had one prier games with malz and it wasn't even jg, and he went 1/8/1). Now I have no idea how to handle this issue, because the best solution would to kick people pre-game, but that's unfair as just because it's weird doesn't mean i cannot work. Best idea I can come up with is pre-game if you have someone making a "troll" pick, you can flag them pre-game, and if you report them afterwards, the troll pick flag is taken into account, giving a heftier punishment in the event there is one. I feel this system is far from perfect (already seeing ways it might be abused), but it's the best I can come up with.
