Getting reported for playing off-meta or doing bad
So I have a short question - can I get punished if I get reported many times for having a bad game or playing off-meta? By Off-meta I mean playing weird champ but fulfilling my role - for example playing Gangplank support, but doing my job as a support - defending ADC, not taking CS and overally helping team like support would do. By doing bad I mean I try my best but get caught / do stupid mistakes or stuff like that that causes me to go for example 2/12.
In 99% of any of those cases people ask enemy team to report me and ofc report me, the thing is - do I need to convince people I'm not trolling, or no matter if they report me or not I will not get punished if I didn't intentionally ruin the game? (Int, grief or flame) I always try to defend my self in all chat that I'm trying but doing bad, cus I'm scared that if I get too many reports I'll get banned, but do I need to, or can I just mute flaming people and keep playing?
