I just don't understand the hate

Hello I play League rift on my phone since 2022 yet I am surprised day by day.

Context: I was only playing casual and when I had time But NOW I'm actually enjoying the game more and I wanna unlock more stuff. With that said I'm still quite new to the game I go jungle cause this is the role I understood really fast and enjoy the most(+if the jungler is bad the game sucks)

My Problem I guess: I just got upgraded to Platinum and damn it's getting more spicy ! But people chat during the game and write to report me for "inting" cause sometimes I die 7 times in one game some other times I make minimum 3 kills most of the times around 5 and the best times are way more like 12. But I don't understand why so mean? why want to report? why also insulting?

Furthermore do you have any advice to die less ig😂Idk I'm just frustrated when you're trying your best and sometimes you just keep getting ganged up by 2 people at once when there was only one to begin with...anyway !

ALSO how to not play with a$$holes?

EDIT : THANK YOU ALL LITERALLY MY LAST GAME WHILE TAKING ALL ADVICES I DID 6/0/6 ranked, game lasted 16:50 SO THANK YOU
