Can I really be banned for not working with my team?

So, I just had my first game with . As usual, I couldn't stay alive, but I was killing the bots with him. But the sad part is, that while I've achieved Level 15 and our Darius did his job. The rest of the team was 2 to 5 levels behind me and we lost.

How you ask? Well the bots' levels were , and 15; 14.

Ours where 10, Darius and 13 and finally was level 12

Although me and Darius intiailly went top, I wound up switiching between mid and bot to kill turrets.

As we were about to lose, I just gave up pushed the bot lane while the rest of the team tried to held base. Someone threatned to report me for not trying to save them. The end result was that I managed to got the enemto recall as I reached the Nexus turret, but we already lost.

Is there anyway that this could've went better?

And more importantly, can I be banned for not working with my team?

But the good news is that I was Honored for being helpful though...
