Deserve to lose over this play?

I was even with my mid opponent for the most part. She got a kill from roaming bot, despite my constant ping spamming, but that is what it is :.

After the play in the video, the team flamed me and spammed for reports for the rest of the game. The nasus was spamming in all chat that I was trolling, and others were agreeing with him. The game was essentially over at that point.

I get it happens, but seriously this made me pretty upset.
