Can I get banned?

So basically today I decided to play AP nunu jungle in ranked game. Everything went well, I helped my team. I've pretty much camped bot lane and got them a huge advantage. We were winning everywhere. Then my team sees I'm building AP nunu and they immediately start flaming me, calling I'm worthless, that I'm shitter and that I should go afk beauce they can easily win 4v5. After that I had enough and went to split push for the entire game and refused to group my team. After that my team lost and everyone said they're going to report me and that I'm going to get banned? Can I really get banned for that?
