Feel like a crap after a match...that I won

So, i was at top lane as going against . Because of rumors that can counter me, i was worried. But this guy was a trolling feeder. Before 15 min mark, he fed me 5 times. He kept diving into my tower, stayed a trade he couldn't win, or run away when his team mate ganked allowing me to kill both her and .

His team absolutely hated him, we hated him for giving us stupid kills, and to top it all off, he kept saying stupid shits ("Remember not to feed guys","OMG bot lane stop playing like an idiot","I'm carrying this team"). Their team ff-ed at 22 min mark, with me going 10/0. Including me, i think everyone reported him afterwards.

I like winning and all, but not against troll/feeder. I don't feel accomplished or anything. I am really annoyed how things turned out
