Ok, I just don't even understand your comment with sens. You say, you got banned, because you are bad at jungling? Does it makes sens? Of course not. You can't be banned because you are bad at League of Legends. It as been a long time since Riot changed that on the system. Report abuse are not taken seriously and so, the system ignore them all. But, if you use some verbal abuse like, shiet, fuk, scrubs ect..., You will certainly get several reports. And also the ennemie team are aware of your toxicity in the game.
Let me tell you something very important, that you are level 2-3 or even 4, you can always gank early game. Putting pressure in a lane early is the most important things as a jungler. Exemple, if I play Irelia Jungle, I will try to gank level 3. If I don't earn a kill, at least, the ennemies is aware that I gank very often. And so, he is afraid because he only has 2 trinkets warding totems and maybe one Vision purple ward. Ganking doesn't mean that you have to kill, no, ganking means putting pressure in all lanes no matter what until they panic and they fail into their plays. You do the rotation between ganks and farms. That is how jungling works.
And if you are banned for a reason you don't want to admit, that's fine, you just deserve it like all the other toxic players. I don't know how many players I've reported for Un-sport-Man like, but I am pretty sur that most of them got a rude warning from the system.
